The number of week for which money is withdraw is 15 weeks .

Step-by-step explanation:

Given as :

Total amount available in account initially = P = $50

The amount need to be in account at the last = p = $20

The amount withdraw each week for food,clothes,ticket = $2

Let The number of week for which money is withdraw = n weeks

According to question

Total amount available in account initially - amount withdraw each week ×  number of week for which money is withdraw = amount need to be in account at the last

i.e $50 - $2 × n = $20

Or, $2 n = $50 - $20

Or, $2 n = $30

∴  n =

i. e n = 15  weeks

So , The number of week for which money is withdraw = n = 15 weeks
