Question

Robert and dustin agree to share the cost of buying a computer that costs $1750. if robert agrees to pay $450 more than dustin, what is the amount that dustin will pay?

Answer 1

r + d = 1750
r = d + 450

d + 450 + d = 1750
2d + 450 = 1750
2d = 1750 - 450
2d = 1300
d = 1300/2
d = 650 <=== what Dustin pays

r = d + 450
r = 650 + 450
r = 1100 ...Robert pays 1100
