The sale price of apples at a local grocery store is $1.35 for the first pound and $1.10 for each additional pound. which function rule shows how the cost of apples, y, depends on the number of pounds, x?

The function that represents this situation is

y = 1.10 (x - 1) + 1.35

y = 1.10 x - 1.10 + 1.35

y = 1.10x + 0.25

y will be dependent on the value of x.

You must subtract one from the x, because the amount you pay for the first pound is already considered in the $1.35.

We have the following variables:

y = the cost of apples

x = the number of pounds

The linear equation that models the problem is:

y = 1.10 (x-1) + 1.35

Answer:

A function rule that shows how the cost of apples, and, depends on the number of pounds, x is:

y = 1.10 (x-1) + 1.35
