Gavin works as a salesperson at an electronics store and sells phones and phone accessories. Gavin earns a $12 commission for every phone he sells and a $3.50 commission for every accessory he sells. On a given day, Gavin made a total of $135 in commission and sold 12 more accessories than phones. Determine the number of phones sold and the number of accessories sold.

Respuesta :

Answer: There are 6 phones and 18 accessories sold.

Step-by-step explanation:

Since we have given that

Let number of phones sold be 'x'

Let number of accessories sold be 'y'.

Commission for every phone = $12

Commission for every accessory = $3.50

Total commission = $135

And Difference between accessories and phones sold = 12

According to question, we get that

[tex]12x+3.50y=135\\\\y-x=12\\[/tex]

Using both the equations, we get that

x=6 and y = 18

Hence, there are 6 phones and 18 accessories sold.
