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
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?
thanks i got the answer
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.

Gabby you're correct that's what i was thinking i thought i was the only one...
To determine the number of weeks it will take Jared to save $100, we need to calculate how much money he saves each week, including the additional money from his mother.
Jared saves $8 each week. In addition, his mother gives him an extra $0.25 for each dollar he saves.
Since Jared saves $8 each week, his total savings without his mother's extra money would be $8 x (number of weeks).
To calculate how much extra money he receives from his mother, we need to determine the amount of money he has saved so far. Assuming he starts with $0, his total savings at the end of each week will be:
Week 1: $8
Week 2: $16
Week 3: $24
Week 4: $32
Week 5: $40
Week 6: $48
Week 7: $56
Week 8: $64
Week 9: $72
Week 10: $80
Week 11: $88
Week 12: $96
So after 12 weeks, Jared would have $96 saved. According to our calculations, he would still need $4 more to reach his goal of $100. Therefore, the answer is not 12 weeks; it would take him a little longer.
To find the exact number of weeks it will take Jared to save $100, we need to divide $100 by the total amount he saves each week, including his mother's extra money.
Each week, he saves $8 + ($0.25 x $8) = $8 + $2 = $10.
Therefore, $100 / $10 = 10.
So it will take Jared 10 weeks to save $100, not 12 weeks. He would not have any money left over since $10 x 10 = $100.
