Question

Write an equation please

Answer 1

Let d represent the amount of money Donavon brought to the fair.

After spending half his money on rides, he had half of it left: d/2.

After spending $3 on food, he had left (d/2 -3).

Donavon and his 3 friends together had 4 times this amount. They had $8.

... 4(d/2 -3) = 8

_____

The solution can be found by simplifying the equation, adding the opposite of the constant on the left, then dividing by the coefficient of d.

... 2d -12 = 8 . . . . . eliminate parentheses

... 2d = 20 . . . . . . . add 12

... d = 10 . . . . . . . . divide by 2

Donavon and each of his friends brought $10 to the fair.
