:
a. If 500 cups were sold for a total of $2,090, how many cups of each type were sold?
:
The no. of cups equation
p + c = 500
p = (500-c); use this form for substitution
;
the cost equation
3.25p + 4.50c = 2090
:
replace p with (500-c)
3.25(500-c) + 4.50c = 2090
:
1625 - 3.25c + 4.50c = 2090
:
-3.25c + 4.50c = 2090 - 1625
:
1.25c = 465
c =
c = 372 ceramic cups
then
500 - 372 = 128 plastic cups
:
What was the dollar value of each type of cup sold?
372 * 4.50 = $1674
128 * 3.25 = $416
