Answer:
2.5x+0.75y=933
x+y=747
Step-by-step explanation:
x= number of cheese sandwiches
y= number of soft drinks
first equation: 2.5x+0.75y=933
**this is representing the cost of the drinks and sandwiches
second equation: x+y=747
**because x and y are the NUMBER of soft drinks and sandwiches, they both have to toal up to 747.

Finished:Left
8:1
8/1 = 72/x
Cross Multiply
8x=72
divide each side by 8
x=9
She already finished 72 and has 9 remaining
Total = Finished + Remaining = 72 + 9 = 81
