Question

question 4
the school cafeteria gets 467 bananas and 312 pears to serve for lunch. during the week, students eat 529 pieces of fruit with their lunch.
which set of equations could be used to find out how many pieces of fruit were left after lunch?

o 467 + 312 = 779
779+ 529 = 1308

o 467 + 312 = 779
779 - 291 = 488

o 467 + 312 = 779
779 - 529 = 250

o 467 - 312 = 155
155 + 529 = 684

question 5
find the sum of 348 + 415

o 762
o 772
o 872
o 874

Explanation:

Step1: Find total fruit

First, find the total number of fruits available initially by adding the number of bananas and pears. So, $467+312 = 779$.

Step2: Find remaining fruit

Then, to find the number of fruits left after students eat 529 pieces, subtract the number of fruits eaten from the total number of fruits available initially. So, $779 - 529=250$.

for Question 5:

Step1: Add the numbers

To find the sum of 348 and 415, add the two - digit numbers. $348+415=(300 + 400)+(40 + 10)+(8 + 5)=700+50 + 13=763$. But it seems there is a mistake in the options provided as the correct sum is 763 and not among the given options. If we assume a calculation - based approach for the options given:
$348+415$:

• Add the units digits: $8 + 5=13$, write down 3 and carry 1.
• Add the tens digits along with the carry: $4+1 + 1=6$.
• Add the hundreds digits: $3+4 = 7$. So the sum is 763.

Answer:

The set of equations $467 + 312 = 779$, $779 - 529 = 250$ is the correct one.
