My friend joop got 14 totts and elentines for about $72. Totts for $8 each and some elentines for $3 each.

1 answer:

7 0

Answer:

Step-by-step explanation:

The variables are defined, so we only need to express the given relations. The total of the two quantities is 14.

x + y = 14

The sum of costs is $72. Totts are $8 each, so x of them will cost 8x. Elentines are $3 each, so y of them will cost 3y.

8x +3y = 72
