Problema Solution
A company that manufactures ink cartridges finds that they can sell x cartridges each week at a price of p dollars each, according to the formula x=3800-100p. What price should they charge for each cartridge if they want to sell 900 cartridges each week?
Answer provided by our tutors
we are given this formula: x=3800-100p
and asked to solve for 'p' when x=900
900 = 3500-100p
p = 26
they should charge $26 for each cartridge
