At a local bakery,single crust pie sell for 5.99 and double crust pies sell for 9.99. The total number of pies sold on Monday was 25. If the sale total for Monday was 189.75 for these two types of pie find the number of each sold.
----
Quantity:: s + d = 25
Value: 599s + 999d= 18975 cents
--------------------------------
599s + 599d = 599*25
599s + 999d = 18975
-----
Subtract and solve for "d":
400d = 4000
d = 10 (# of double crust pies)
----
Solve for "s"::
s = 25-10 = 15 (# of single crust pies)
