Problema Solution
Lisa started a small business selling roses and carnations. Yesterday, she sold a total of 100 flowers for $256. If a rose cost %3 dollars and a carnation cost $2 dollars, how many of each flower did she sell?
Answer provided by our tutors
let 'r' represent the number of roses sold, then '100-r' represents the number of carnations sold
we then have this equation:
256 = 3r + 2(100-r)
solving for 'r' we have:
r=56
100-54 = 44
Lisa sold 56 roses and 44 carnations
