Problema Solution
A busload of campers stopped at a dairy stand for ice cream. They ordered 66 cones, some soft-serve at $1.50 each and the rest hard-pack at $0.50 each. If the total bill was $72.00, how many of each type of cone were ordered?
How many soft-serve cones were ordered?
Answer provided by our tutors
Let
s = soft-serve cones
h = hard-pack cones
There were 66 cones ordered in total:
s + h = 66
The total bill was $72 means:
1.50s + 0.50h = 72
We have the following system of equations:
s + h = 66
1.50s + 0.50h = 72

........
s = 39 soft-serve cones
h = 27 hard-pack cones
There were 39 soft-serve and 27 hard-pack cones ordered.
