Shirley is saving money to buy a new computer. The computer she will buy costs $1,200.
She has already saved 300. Shirley will save another $60 each week, until she has saved enough money to buy the compute. How many weeks will it take Shirley to save enough money to buy the computer?
x = number of weeks to save {the unknown}
Create an equation: (amount saver per week times number of weeks) plus (amount already saved) = total amount 60x + 300 = 1200 60x = 900 {subtracted 300 from each side} x = 15 {divided each side by 60} she must save for 15 weeks Ask the House
