Problema Solution
200 flowers. Carnations at $1.50 each, roses at $5.75 each, and daisies at $2.60 each. They ordered mostly carnations, and 20 fewer roses than daisies. Total odder came to $589.50. How many of each type of flower was ordered?
Answer provided by our tutors
let
c = the number of carnations ordered
r = the number of roses ordered
d = the number of daises ordered
c + r + d = 200
They ordered mostly carnations, and 20 fewer roses than daisies
r = d - 20
Total odder came to $589.50
1.50*c + 5.75*r + 2.60*d = 589.50
by solving the system of equations
c + r + d = 200
r = d - 20
1.50*c + 5.75*r + 2.60*d = 589.50
we find
c = 80 carnations
d = 70 roses
r = 50 daisies
