Problema Solution
A firm pays $1.75 for each copy of a magazine and sells each one for $2.50. There is a fixed monthly cost of $40 for printing the publication. If the firm wants to make $550 dollars next month, how many magazines do they have to sell? Write and solve an equation that represents this scenario.
Answer provided by our tutors
let 'x' be the number of magazines they need to sell
the revenues from the sales - the total money spent for printing = the profit of $550
x*2.50 - (40 + x*1.75) = 550
by solving the equation we find
x = 787 magazines
