Question

The ratio of the price of a cheeseburger to the price of a soda at a restaurant is 3 to 2. If a cheeseburger costs $2 more than a soda, what is the price of a soda?

Answer 1

= $4

Explanation:

Total price = 3 + 2 = 5

= 3 - 2 = 1

Soda

If 1/5 = $ 2

What about 2/5 = ?

= (2/5 x 2) ÷ 1/5

= 4/5 ÷ 1/5

= 4/5 x 5

= $4

Cheeseburger

If 1/5 = $ 2

What about 3/5 = ?

= (3/5 x 2) ÷ 1/5

= 6/5 ÷ 1/5

= 6/5 x 5

= $6

Total

= 6 + 4

= $10
