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!

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?

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.
