Question

the sale of apples at a local grocery store is $1.35 for the first pound and $1.10 for each additional pound. What function rule shows how the cost of apples, (Y), depends on their number of pounds, (X).

A: y=1.10(x-1)+1.35
B: y=1.10x+1.35
C: y=1.35x+1.10
D: y=(1.10+1.35)x

Answer 1

B: y=1.10x+1.35

Answer 2

The correct function rule that shows how the cost of apples (Y) depends on the number of pounds (X) is:

B: y = 1.10x + 1.35

This is because the cost of apples is $1.35 for the first pound, and for each additional pound, it costs $1.10. Adding $1.10 for each additional pound translates to adding 1.10x to the cost, where x is the number of pounds.
