Answer:
Number of men's shoes = x = 9 shoes
Number of women's shoes = y = 27 shoes
Step-by-step explanation:
A shoe store pays 1980$ a month for rent. The average profit on each pair of men's shoes is $25, and the average profit on each pair of wemons shoes is $65. .How many pairs of shoes of each type of shoe must the store sell each month to pay the rent?
Number of men's shoes = x
Number of women's shoes = y
The system of equations is given as:
$25 × x + $65 × y = $1980
25x + 36y = $1980..... Equation 1
They usually sell 3times as many pairs of wemons shoes as men's
y = 3x
25x + 65y = $1980..... Equation 1
25x + 65(3x) = 1980
25x + 195x = 1980
220x = 1980
x = 1980/220
x = 9 shoes
y = 3x
y = 3(9)
y = 27 shoes
Number of men's shoes = x = 9 shoes
Number of women's shoes = y = 27 shoes
