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

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
