Question

what does your answer of 6 mean in this situation?
7r + 5 = 47
r = 6
jiro can go to the fair for 6 hours to spend $47.
jiro can ride 6 rides to spend $47.
jiro needs to spend $6 on rides to spend $47.

Explanation:

In the equation \(7r + 5 = 47\), \(r\) likely represents the number of rides (since the context is about a fair and spending money on rides, with a fixed cost of 5 and a per - ride cost of 7). Solving gives \(r = 6\), so it means Jiro can ride 6 rides to spend $47. The first option refers to hours, but there's no indication \(r\) is hours. The third option misinterprets the meaning of \(r\) as a cost per ride - related amount, but \(r\) is the number of rides.

Answer:

Jiro can ride 6 rides to spend $47.
