Question

The cost of apples can be modeled by the equation f(x) = 0.80x, where

f(x) is the cost and x is the weight of apples in pounds. How much do
3.25 pounds of apples cost?

Answer 1

2.6

Explanation:

Given:

f(x) = 0.80x

where,

f(x) = the cost

x = weight of apples in pounds

Pounds of apples = 3.25 pounds

Find the cost?

f(x) = 0.80x

Substitute into the equation x = 3.25

f(x) = 0.80x

= 0.80(3.25)

= 2.6

f(x) = 2.6

Therefore, the cost of 3.25 pounds of apples is 2.6
