The cheddar cost 7.95 per pound, and the swiss cost 9.50 per pound. lori bought five and a half pounds of cheese for s total of 47.60

Cheddar = 3 lbs, Swiss = 2.5

Step-by-step explanation:

                      Quantity            Cost

Cheddar                x                 7.95                                        

Swiss                     y                 9.50

Total:                     5.5             47.60

Qty: x + y =  5.5    ⇒   -7.95(x + y = 5.5)   ⇒  -7.95x -7.95y =  -43.725                              

Cost: 7.95(x) + 9.50(y) = 47.60  

Use elimination to solve.

 -7.95x  - 7.95y  =  -43.725      

7.95(x) + 9.50(y) = 47.60

                1.55y   = 3.875

              ÷ 1.55 ÷ 1.55    

                       y  =  2.5

Qty: x + y =  5.5

     x + 2.5 = 5.5

         -2.5  -2.5

     x          = 3.0
