Mari works part time selling both hats and scarfs. One week she earns $114.00 by selling eight hats and 10 scarves. The following week she sold 12 hats and six scarves and earned $108.00. How much does she earn for each hat and scarf she sells?

Respuesta :

Using a system of equations, it is found that she earns $5.5 for each hat and $7 for each scarf sold.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Cost of a hat.
  • Variable y: Cost of a scarf.

One week she earns $114.00 by selling eight hats and 10 scarves, hence:

8x + 10y = 114.

The following week she sold 12 hats and six scarves and earned $108.00, hence:

12x + 6y = 108

Simplifying by 6:

2x + y = 18

y = 18 - 2x.

Replacing in the first equation:

8x + 10y = 114.

8x + 10(18 - 2x) = 114

12x = 66

x = 66/12

x = 5.5

y = 18 - 2x = 18 - 2 x 5.5 = 7.
