How much WS my pocket money
To find out how much pocket money Joe had, we can set up an equation based on the given information.
Let's say Joe's pocket money is represented by the variable "x". According to the problem, he spends a fifth (1/5) of his pocket money and is left with £2.
We can set up the equation as follows:
x - (1/5)x = £2
To simplify the equation, we can find the common denominator and subtract the fractions:
(5/5)x - (1/5)x = £2
(4/5)x = £2
To isolate the variable, we can multiply both sides of the equation by the reciprocal of the coefficient of x (in this case, 5/4):
(4/5)(5/4)x = £2(5/4)
x = £2.50
Therefore, Joe had £2.50 as his pocket money.
