Ms. kendrick plans to buy a laptop for $1,345 in 12 weeks. she has already saved $145. how much should she save each week so she can buy the laptop?

1345 - 145 = 1200

She needs to save $1,200 in 12 weeks, now divide thow much she needs to save by the number of weeks to find how much she needs to save each week:

1200 / 12 = 100

She needs to save $100 per week.

x = 90/3

x = 30
