Question

My weekly pay is increased by $100 per week. Half of my pay now goes to pay the rent and $100 to buy groceries. If this leaves me with $35, what was my original pay?

Answer 1

Let my original weekly pay = x dollars.

Then:-

x + 100 - [0.5(x + 100) + 100] = 35

x + 100 - 0.5x - 50 - 100 = 35

0.5x = 35 + 50

x = 85 / 0.5 = 170 dollars answer
