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?
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
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.

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.
The correct function rule that shows how the cost of apples, y, depends on the number of pounds, x is:
A: y=1.10(x-1)+1.35
