Question

Sam paid $9.00 for 20 pieces of candy. At this price, how much would it cost Sam to buy 12 pieces of candy?

Answer 1

$5.40

Explanation:

`(9)/(20) = (x)/(12)` represents this situation. Cross multiply to get 20x = 108. Divide 20 from both sides to get x on its own. 20x divided by 20 is x. 108 divided by 20 is 4.5. 4.5 in money is the same as 4.50 dollars.

Hope it helps!

Answer 2

$5.40
Explanation: it would be 45 cents per candy. .45•12=5.40
