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.
