Answer 5

1) Calculate a unit rate. $0.90/(3 apple) = 30¢ / apple. Now, how much for 10 apples?

2) Set up a proportion. \(\dfrac{90¢}{3\;apples} = \dfrac{What}{10\;apples}\)

3) Can you think of another way?

Answer 6

That's how you do it. ^

Answer 7

I agree....I myself would probably do it the proportion way

Answer 8

Yeah the proportion way is easier to me. But whatever works best.

Answer 9

Just remember you are working in pennies.

3) Set up a function! After calculating the unit rate, Price(Apples) = 0.30*Apples. Substitute the desired value and you are done.
