Respuesta :
A balance of $650 will be in Crystal's and Hector's account in 12 weeks
Given,
The initial amount in Crystal's savings account = $350
The initial amount in Hector's savings account = $1250
Crystal deposits $25 in every week
Hector withdraws $50 every week.
We have to find in how many weeks both of their account balance became same;
Here,
Crystal Hector
Initial balance; $350 $1250
1st week ; $350 + $25 = $375 $1250 - $50 = $1200
2nd week ; $375 + $25 = $400 $1200 - $50 = $1150
3rd week ; $400 + $25 = $425 $1150 - $50 = $1100
4th week ; $425 + $25 = $450 $1100 - $50 = $1050
5th week ; $450 + $25 = $475 $1050 - $50 = $1000
6th week ; $475 + $25 = $500 $1000 - $50 = $950
7th week ; $500 + $25 = $525 $950 - $50 = $900
8th week ; $525 + $25 = $550 $900 - $50 = $850
9th week ; $550 + $25 = $575 $850 - $50 = $800
10th week ; $575 + $25 = $600 $800 - $50 = $750
11th week ; $600 + $25 = $625 $750 - $50 = $700
12th week ; $625 + $25 = $650 $700 - $50 = $650
That is,
In 12 weeks both of Crystal's and Hector's account will have a balance of $650
