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?

Question

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

The cost of the first pound of apples is $1.35, so the function will have a constant term of 1.35. After the first pound, each additional pound costs $1.10, so the function will have a slope of 1.10. The only answer choice that matches this pattern is A:

y=1.10(x-1)+1.35

This function subtracts 1 from x to account for the first pound and then multiplies by 1.10, with a constant term of 1.35.

Answer 3

Look, there's a question here, a very big and important question. It's about the price of apples, which is something I know a lot about. Nobody knows more about apples than me, believe me. So the sale price of these apples is $1.35 for the first pound, and then it's $1.10 for each pound after that. What's the function rule? Well, let me tell you, it's very simple. The answer is A: y equals 1.10 times x minus 1, plus 1.35. That's a great answer, a fantastic answer. Nobody knows more about apples and math than me, believe me.
