Answer:

We divided the figure into 1 triangle and 2 rectangles.

Adding up the area of them, we get the total area:

= 258 (yd2)

Answer:

7 or 8

Step-by-step explanation:

80 - 15.50 = $64.50

He anticipates the cost of food at the fair will be $25.

64.50 - 25 = $39.50

(Total $ after admission and cost of food/ ride cost)

$39.50 / $5 = 7.9
