Set up an equation based on the information given.

12x + 145 = 1345

Solve the equation to see how much she needs to save each week.
First, subtract 145 from both sides.

12x = 1200

Divide 12 off of both sides to find the value of x. 

x = 100

She needs to save 100 dollars each week, for 12 weeks to buy the laptop.
