Question

pedro opened his account with $710 and withdrew $35 per week. maria opened her account with $570 and withdrew $25 weekly. in how many weeks will their accounts be equal.

Answer 1

14 weeks and then they will be the same

Answer 2

Going by the amounts they started with and the amounts they withdraw per week, Pedro's account will equal Maria's after 14 weeks.

Pedro started with $710 in his account and withdraws $35 weekly. Assuming the number of weeks was x, after x weeks, Pedro's account would have:

= Amount started with - (Amount withdrawn per week x Number of weeks)

= 710 - 35 × x

= 710 - 35x

For Maria, the account balance would be:

= 570 - 25x

To find the number of weeks till their accounts are equal, equate the formulas:

710 - 35x = 570 - 25x

710 - 570 = -25x + 35x

140 = 10x

x = 140 / 10

x = 14 weeks

In conclusion, their account balances would be the same after 14 weeks.
