Lizeth Levy · Answer 2

x = 14 weeks

Therefore the money will last for 14 weeks

Step-by-step explanation:

Given;

Initial amount = $550

Final amount = $200

Weekly Withdrawal = $25

Let x represent the number of weeks the money would last;

The sum of weekly Withdrawal for x weeks is = $25x

The problem can then be represented by the equation.

550 - 25x = 200 ... 1

Making x the subject of formula, we have;

25x = 550-200

x = (550-200) / 25 = 350/25

x = 14 weeks

Therefore the money will last for 14 weeks
