(c) Check your solution. Show your work.
(d) State the solution in complete sentences.
Answer:

Answer 1

one Brian's item cost: x

one Chris' item cost: x+2.5

Set up equation:

Brians amount = Chris amount

4*x = 3*(x+2.5)

solve for x:

4x = 3x + 7.5

x = 7.5

Brian's items cost $7.5 each.

Check:

Brian paid 4*7.5 = $30

Chris paid 3*10 = $30

The individual cost of Brian's items was $7.50, and the indiv. cost of Chris' items was $10.
