Question

Ten frozen juice bars cost $7.90. how much would 50 juice bars cost?
​

Answer 1

$39.50

Explanation:

Multiply 7.9 by 5 to get 39.5

Answer 2

if 10 of them costs $7.90 then 50 would cost $39.50.

there are two different ways of doing this:

1. you could divide $7.90 by 10 which would get you $0.79 (the price of one frozen juice bar) then multiply $0.79 by 50 to get $39.50 (the price of 50 frozen juice bars)

or

2. you could just take $7.90 and multipy it by 5 (b/c 10 x 5 is 50)
