To calculate how much 9 apples cost, you must multiply 9 to 4.55 and then divide by 7. This is done by setting up a proportion.
For either one of the deals, just find what one card equals and times it by how many cards the other equation has.
e.g. 0.35 cents divide by 10 = 0.035. And now, you times it by 12 since the other deal is 12 cards for 40 cents.
0.035 x 12 = 0.48
So, 10 cards for 35 cents is not the better deal.
