Problema Solution
A florist wishes to make bouquets of mixed spring flowers. Each bouquet is to be made up of tulips at $30 a bunch and daffofils at $21 a bunch. How many bunches of each should she use to make 15 bunches which she can sell for $24 a bunch?
Answer provided by our tutors
Let t=number of tulips
d=number of daffodils
d+t=15
30t+21d=24(15)=360
d+t=15
30t+21d=360
10t+7d=120 (1)
multiplying both sides of d+t=15 by 10 we get
10t+10d=150 (2)
subtract (1) from (2)
3d=30
d=10
10+t=15
t=5
The number of daffodils is 10 and the number of tulips is 5.
