Question 822662: sunrise record is having a music sale. every cd(c) in the store is the same price and every tape(t) is another price. Three cd's and two tapes will cost $67. one cd and three tapes will cost $48. This situation can be represented by the FF system of equation: 3c+2t=67, c+3t=48 solve the system to determine the cost of each CD and each tape. Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! Multiply the "48" equation by 3, and subtract one equation from the other equation. Solve then for t, first.
