Problema Solution
A business is considering two companies where they can purchase promotional coffee mugs to give away to thier customers. Promostuff sells them for $0.93 each plus charges $20 per order and Stuff2give sells them for $0.87 each plus a charge of $35 per order. For what number of coffee mugs is the total order cost the same from either company.
Answer provided by our tutors
Let the number of coffee mugs be x.
If the cost for both must be equal, then
20+0.93x=35+0.87x
Taking x terms to one side,
x(0.93-0.87)=35-20
x=15/6=2.5
