Question

jiro has $47 to spend at the fair. the entrance fee to the fair is $5, and the rides cost $7 each. how many rides can jiro go on to spend exactly $47? solve for the value of r. solve on paper, or show your work below. then enter your answer on zearn. 7r + 5 = 47 r = \square

Explanation:

Step1: Subtract 5 from both sides

To isolate the term with \( r \), we subtract 5 from both sides of the equation \( 7r + 5 = 47 \). This gives us \( 7r + 5 - 5 = 47 - 5 \), which simplifies to \( 7r = 42 \).

Step2: Divide both sides by 7

To solve for \( r \), we divide both sides of the equation \( 7r = 42 \) by 7. So, \( \frac{7r}{7} = \frac{42}{7} \), which simplifies to \( r = 6 \).

Answer:

\( r = 6 \)
