Jared wants to save \$100 to buy a tennis racket. He saces \$8 each week, and his mother gives him a extra \$0.25 for each dollar he saves.

Determine the number of week it will take Jared to save \$100.

I am pretty sure the answer is 12 weeks and he would have \$5 dollars left over. Can you please check for me? Thank you!

Sorry that is suppose to be He saves \$8

• 7th grade math -

So he gains \$8.25 each week

100/8.25 = 12.12

this tells us that he needs slightly more than 12 weeks to get to \$100

check: 12x8.25 = \$99

Since there will probably be tax on his purchase, he must save for 13 weeks buy the tennis racket.

Actually, his mother is more generous because she gives him \$0.25 for every dollar he saves. So each week he comes up with
\$8 + 8*0.25=\$10

Can you figure out the rest?

He has 13 weeks with some extra money left over!!!

The answer is 10 weeks. His mother is giving him .25 for every dollar. He saves \$1, he gets .25, \$2, he gets .50, etc. In one week, he gets \$10. 10 times 10 is 100.
