Question

three brother spent different amount of money on their recent vacation. matt spent $25 less than todd. jeff spent 3 times as much as matt. how much spend if they spent a total of $275

Answer 1

We can have different variables to represent each brother (there can be different variations and ways to solve, but I'll do it my way).

Matt=m
Jeff=3m
Todd=m+25

Matt Jeff Todd
m+3m+(m+25)=275 3(50) 50+25
5m+25=275 =150 =75
5m=250
m=50

Matt spent $50, Jeff spent $150 and Todd spent $75

Check:
50+150+75
=$225
