Answer:
x = 14 weeks
Therefore the money will last for 14 weeks
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
