Question

Sally is saving money to buy a new computer. The computer costs $689. She has saved $125, and each week she adds $25 to her savings. Assuming that she deposits her money once a week, how many weeks will it take her to save enough money to buy the computer?

Answer 1

Explanation:

the amount of money she would need would be 700 dollars because the money she gets isn't continuous but discrete

700 - 125 = 575

575 / 25 = 23

23 should be the answer

Answer 2

23 because you also subtract the amount of weeks you already saved up

Explanation:

if you want ecxactness 689 divided by 25 is

or if you want approxiamte i rounded 689 up to 700 because we want to know how many weeks and we will have passed 689 so yeah.

Then i divided 700 by 25 and i got 28

then subtract 125 from 700 and you get 675 ND THEN DIVIDE THAT BY 25 and you get 23
