how many weeks will he have enough saved up to buy it?

Question

Diego is saving up for new shoes for $128. He has $7 saved. If he saves $11 per week, in how many weeks will he have enough saved up to buy it?

Answer 1

To determine how many weeks it will take Diego to buy new shoes, we can do the following calculation:

Starting money - $7

Because Diego has already saved 7 dollars, we are able to subtract this from the total amount of money($128) that he needs to save.

Remaining amount of money to save: $121

We know that Diego will save $11 each week. With this in mind, we should divide the remaining amount he needs to save($121) by the amount that he saves each week($11).

After this calculation, we can determine that it will take Diego 11 weeks to save up enough money to buy new shoes.

Answer 2

The total money he needs is $128. Diego is starting with $7. If you subtract 7 from 128, you will find out that Diego needs $121. So, now we need to figure out how long it will take for Diego to save up $121, if he is saving $11 a week.

1 week-$11

5 weeks- $55

10 weeks- $110... we are close, let's go up 1 week at a time now

11 weeks-$121.. That's it!

It would take 11 weeks to save up enough money

Answer 3

To determine the number of weeks Diego will need to save up enough money to buy the new shoes, we can use the following calculation:

Amount Diego needs to save = Cost of shoes - Amount he already saved up prior to

Amount Diego needs to save = $128 - $7

Amount Diego needs to save = a total of $121

Diego savings per week = $11

Number of weeks Diego needs = Amount needed to save / Saving per week

Number of weeks Diego needs = $121 / $11

so 11 weeks is what Diego needs to save up enough money to buy his new shoes.

Answer 4

(128-7)/11 = 121/11= 11 weeks to save 128
