Problema Solution

roses cost $3 each and tulips cost $2 each. Carlos spent $29 in purchasing 11 flowers for Rafaela. How many of each flower did he buy?

Answer provided by our tutors

let 'x' represent the number of roses Carlos purchcased, then '11-x' represents the number of tulips Carlos purchased

we assume the cost either includes or ignores sales tax... the total cost can be expressed as an equation:

29.00=3.00x+2.00(11-x)

x=7

11-7=4

So Carlos purchased 7 roses and 4 tulips for Rafaela.
