Riley is saving up to buy a new television. She needs a total of $1,217.74. Riley has saved $200.36 already and earns $78.26 per week at her job. How many weeks does Riley need to work to save enough money to buy the new television?

13 weeks

Step-by-step explanation:

1,217.74 = 200.36 + 78.26w (w represents number of weeks)

Subtract 200.36

1,017.38 = 78.26w

Divide by 78.26 on both sides

w = 13

Riley will need to save money for 13 weeks to afford the new television.

I hope this helps!!
