Question

Latoya is saving money at a constant rate to buy a new computer. The table below shows the amount of money that Latoya still needs to purchase the computer.

How many dollars is Latoya saving each week?

Answer 1

630-450= 180

there were three weeks between these two amounts

180/3 = 60

450-330= 120

there were two weeks between these two amounts

120/2 = 60

330-210 = 120

again two weeks between amounts

120/2 = 60

It can now be said that LaToya is saving $60 per week
