Harper works at an electronics store as a salesperson. harper earns a 6% commission on the total dollar amount of all phone sales she makes, and earns a 5% commission on all computer sales. harper made a total of $2600 in sales and earned $137 in commission. write a system of equations that could be used to determine the dollar amount of phone sales harper made and the dollar amount of computer sales she made. define the variables that you use to write the system.

The system of equations are

x + y = 2600  …….equation (1)

and, 6x + 5y = 13700  ……equation (2)

Explanation:

Let x = amount of sales of phone;

y = amount of sales of computer

For phone, 6% of sales is 6% of x, or 6% * x = 0.06x.

Similarly for computer,

5% of y = 0.05y

Given the total sales; x + y = 2600

And commission; 0.06x + 0.05y = 137; or 6x + 5y = 13700

Therefore the system of equations are

x + y = 2600  …….equation (1)

6 x + 5 y = 13700  ……equation (2)
