Question

write an equation that represents this situation where p represents the total percent.
visitors
0 2,200 3,520
0% 100% ?
□□□ = □

• 1,320 100 p 2,200 3,520 + ·

Explanation:

Step1: Analyze the relationship

We know that 2200 corresponds to 100%, and we want to find the percentage \( p \) for 3520. The relationship between the number of visitors and the percentage should be proportional. So we can set up a proportion: \(\frac{3520}{2200}=\frac{p}{100}\), which can be rewritten as \( 2200 \cdot \frac{p}{100}=3520 \) or more simply, using the idea that the percentage \( p \) of 2200 is 3520? Wait, no, actually, 2200 is 100%, so to find what percent 3520 is of 2200? Wait, no, looking at the number line: the first number line has 2200 at a mark, and 3520 at the end. The second number line has 100% at the 2200 mark, and we need to find \( p \) at 3520. So the ratio of the numbers should equal the ratio of the percentages. So \( \frac{3520}{2200}=\frac{p}{100} \), cross - multiplying gives \( 2200p = 3520\times100 \)? Wait, no, maybe a simpler way: since 2200 is 100%, then the equation should be based on the proportion. Let's think of it as: the number of visitors and the percentage are proportional. So \( \frac{3520}{2200}=\frac{p}{100} \), which can be rearranged to \( 2200\times\frac{p}{100}=3520 \), but looking at the given numbers, the correct equation is \( 2200\cdot\frac{p}{100}=3520 \), but with the given tiles, we can write it as \( 2200\times p\div100 = 3520 \), or using the tiles, the equation is \( 2200\cdot\frac{p}{100}=3520 \), which can be written as \( 2200 \cdot p \div 100=3520 \), but with the given operation tiles (the dot is multiplication, and we have 100, p, 2200, 3520). So the correct equation is \( 2200\times p\div100 = 3520 \), but using the tiles, we can form \( 2200 \cdot \frac{p}{100}=3520 \), which is equivalent to \( 2200\times p\div100 = 3520 \). But looking at the tiles, we have 2200, the dot (multiplication), p, divided by 100 (but we have 100 as a tile). Wait, the tiles given are: 2200,., p, 100, =, 3520? No, wait the tiles are: -, 1320, 100, p, 2200, 3520, +,.. So the correct equation is \( 2200\times p\div100 = 3520 \), which can be written as \( 2200 \cdot p \div 100=3520 \), but with the tiles, we can use \( 2200 \cdot \frac{p}{100}=3520 \), so the equation is \( 2200 \times p \div 100 = 3520 \), but using the given tiles, we can arrange it as \( 2200 \cdot p \div 100 = 3520 \), but the way to write it with the tiles is \( 2200 \times p \div 100 = 3520 \), but since we have to use the tiles provided (the numbers and operations), the equation is \( 2200 \cdot p \div 100 = 3520 \), which is \( 2200 \times p \div 100 = 3520 \). But let's check the proportion again. If 2200 is 100%, then \( \frac{2200}{100}=\frac{3520}{p} \)? No, that's the other way. Wait, no: percentage \( p \) of 2200 is 3520? No, 2200 is 100%, so 3520 is a larger number, so it's more than 100%. So the correct proportion is \( \frac{3520}{2200}=\frac{p}{100} \), so cross - multiplying: \( 2200p = 3520\times100 \), so \( p=\frac{3520\times100}{2200} \), but the equation we need to write is \( 2200\times\frac{p}{100}=3520 \), which is the same as \( \frac{2200p}{100}=3520 \). So using the tiles, we can write \( 2200 \cdot p \div 100 = 3520 \), which is \( 2200 \times p \div 100 = 3520 \). So the equation is \( 2200 \times p \div 100 = 3520 \), but with the given tiles (the dot is multiplication, and we have 2200, p, 100, and 3520), so the equation is \( 2200 \cdot p \div 100 = 3520 \), which can be written as \( 2200 \times p \div 100 = 3520 \).

Step2: Form the equation with tiles

We have the numbers 2200, p, 100, and 3520, and the operations (multiplication dot, and division is implied by dividing by 100, but since we have 100 as a tile, we can write it as \( 2200 \times p \div 100 = 3520 \), which using the given tiles (the dot is multiplication, and we can use the multiplication and then division by 100) is \( 2200 \cdot p \div 100 = 3520 \), but in the tile - based equation, we can write it as \( 2200 \times p \div 100 = 3520 \), so the equation is \( 2200 \times p \div 100 = 3520 \), which is \( 2200 \cdot p \div 100 = 3520 \).

Answer:

\( 2200 \times p \div 100 = 3520 \) (or using the tile arrangement: \( 2200 \cdot p \div 100 = 3520 \))
