Question 1205371: A boy spends 57% of his pocket money. If the amount that he spends is ₦7 more than he has left, how much money had he originally? Answer by math_tutor2020(3817) (Show Source):

x = starting amount of money
0.57x = amount spent
x - 0.57x = 0.43x = amount leftover
He spent 57% of his money and keeps the remaining 43%.
The phrase "the amount that he spends is ₦7 more than he has left" leads to the equation: 0.57x = 0.43x+7
Let's solve for x.
0.57x = 0.43x+7
0.57x - 0.43x = 7
0.14x = 7
x = 7/0.14
x = 50
