Grandma's bakery sells single crust pies for $6.99 and double crust pies for $10.99. The total number of pies sold on a busy Friday was 36. If the amount collected for all the pies that day was $331.64, how many of each type were sold?
Answer provided by our tutors
let
x = the number of single crust pies
y = the number of double crust pies
The total number of pies sold on a busy Friday was 36:
x + y = 36
If the amount collected for all the pies that day was $331.64:
6.99x + 10.99y = 331.64
by solving the system of equations:
x + y = 36
6.99x + 10.99y = 331.64
we find:
x = 16 single crust pies
y = 20 double crust pies
