Admission to the carnival on Friday is $8.00 and each ride costs $1.50. Admission to the carnival on Saturday is $10 and each ride costs $1. Which inequality would be used to find the minimum rides needed so that Saturday's total cost is less than Friday's total cost?

8 + 1.50 r > 10 + r 8\ +\ 1.50r\ >10\ +\ r 8 + 1 . 5 0 r > 1 0 + r

8 + 1 r > 10 + 1.50 r 8\ +\ 1r\ >10\ +\ 1.50r 8 + 1 r > 1 0 + 1 . 5 0 r

8 + 1 r < 10 + 1.50 r 8\ +\ 1r\ <10\ +\ 1.50r 8 + 1 r < 1 0 + 1 . 5 0 r

8 + 1.50 r < 10 + r 8\ +\ 1.50r\ <10\ +\ r 8 + 1 . 5 0 r < 1 0 + r

The model represents an equation. Write the equation and solve for x.

− 3 x + 2 = 5 x − 8 , x = 1.25 -3x\ +2\ =\ 5x\ -8,\ x=1.25 − 3 x + 2 = 5 x − 8 , x = 1 . 2 5

− 3 x + 2 = 5 x − 8 , x = 0.8 -3x\ +2\ =\ 5x\ -8,\ x=0.8 − 3 x + 2 = 5 x − 8 , x = 0 . 8

3 x + 2 = 5 x + 8 , x = − 3 3x\ +2\ =\ 5x\ +8,\ x=-3 3 x + 2 = 5 x + 8 , x = − 3
