Problema Solution
The school band sells carnations on Valentine's Day for $2 each it buys the carnations from a florist for $0.50 each, plus $16 delivery charge. When will the cost of the carnations be equal to the revenue does it need to sell to reach this point?
Answer provided by our tutors
To cover the cost of a $16 delivery charge, 'x' number of carnations must be sold for $2 each with a cost of $0.50 each:
2x-0.5x=16
x=10.67
So 11 carnations need to be sold in order to cover the $16 delivery charge.
