Problema Solution

a firm pays $1.75 for each copy of a magazine and sells each one for $2.50. There is a monthly cost of $40 for printing and publication. If the firm wants to make $550 dollars next month, how many magazines do they have to sell

Answer provided by our tutors

let 'x' represent the number of magazines to sell in order to make $550 (profit, we assume)


the equation for the total can be expressed as:

T = (2.50 - 1.75)x - 40


let 'T' represent the total:

550 = (2.50 - 1.75)x - 40

---------------------------

solve for the number of magazines, 'x'

---------------------------

x=680


The firm must sell 680 magazines in order to make $550 dollars next month.
