Answer 1

Answer:

Option d is correct

50 male customers does he need to meet his expenses

Step-by-step explanation:

Here, x is the number of women's shoes and y is the number of men's shoes designed by Javier.

As per the statement:

Javier designs leather shoes at his workshop.

He charges $45 for women's shoes and $50 for men's shoes.

Total charges for women shoes = 45x

Total charges for women shoes = 50y

It is also given that he needs to make $2,500 per week to meet his expenses.

⇒$45x+50y = 2500$               ......[1]

Since,  if he does not have any female customers during a particular week.

⇒x = 0

Substitute this in [1] we have;

$45(0)+50y = 2500$

⇒$50y = 2500$

Divide both sides by 50 we have;

y =50

Therefore, 50 male customers does he need to meet his expenses.

Answer 2

45x + 50y = 2500

45(0) + 50y = 2500

50y = 2500

y = 50
