Plate Cup
The total cost of 2 plates and 3 cups is $36. The cost of the cup is 2/3 the cost of the plate. How much does?
Let plates=p and cups=c
Then we have:
1) 2p+3c=36
2) 2/3*p=c
a) Plug in 2/3p for c in equation 1.
2p+3*2/3p=36
2p+2p=36
4p=36
p=9
2*9+3c=36
18+3c=36
3c=18
c=6
Thus, plates are 9 dollars each and cups are six dollars each.
