Problema Solution
staples sells boxes of pens ($10) and rubber bands ($4). Leona ordered a total of 24 cartons for $210. How many boxes of each did Leaona order?
Answer provided by our tutors
let 'x' represent the number of pens, then '24-x' represents the number of rubber bands
210 = 10x + 4(24-x)
solving for 'x' we have x=19
24-19 = 5
Leona ordered 19 boxes of pens and 5 boxes of rubber bands
