Question

1. Donavon and three friends go to a fair. Each person brings the same amount of money. They each spend of their money on rides. Then they each spend $3 on food At the end of the day, Donavon and his friends have a total of $8 remaining. How much money did each person bring to the fair?​

Answer 1

Each person brought $10 to the fair

Explanation:

let x = amount each person brought to the fair

Donavon + 3 friends = 4 people

(4x)/2 - $3(4) - $8 = 0

Each of the 4 people spent half their starting money on rides, then $3 each on food, with $8 leftover total.

Solve for x:

2x - 12 - 8 = 0

2x = 20

x = 20/2 = 10

Check the answer:

$10(4 people) - ($10/2)(4 people) - $3(4 people) = $40 - $20 - $12 = $8 left

answer is correct!
