Question

The amount of money Emily spends, after r rides, at a carnival

Answer 1

The coordinate of a function are written in the form (x, y). The coordinates (11, 108) and (15, 140) satisfy the function

Coordinate of a function

The coordinate of a function are written in the form (x, y)

Given the amount of money Emily spends, after r rides, at a carnival

is modeled by the function y = 8r + 20

We are to determine the coordinate that satisfies the function

For the coordinate (15, 140)

If r = 15, then

y = 15(8) + 20
y = 140

Hence the coordinate (15, 140) satisfy the function

For the coordinate (11, 108)

If r = 11, then

y = 11(8) + 20
y = 108

Hence the coordinate (11, 108) satisfy the function
