Johnny is saving money for a concert ticket that costs $48. He has already saved up $12. He plans to save $3 each week. How long will it take Johnny to save enough money to buy the ticket?

w =12

Step-by-step explanation:

He has 12 dollars

He saves 3 dollars a week

12  + 3 w  where w is the number of weeks

He needs 48

12 + 3w = 48

Subtract 12 from each side

12+3w -12 = 48-12

3w = 36

Divide by 3

3w/3 = 36/3

w = 12
