Ashley works as a salesperson at an electronics store and sells phones and phone
accessories, and makes a fixed commission for each phone sale and a different fixed
commission for each accessory sale. yesterday ashley sold 10 phones and 26
accessories and made a total commission of $215. today she sold 5 phones and 21
accessories and made a total commission of $127.50. determine the price of each
phone and the price of each accessory.

accesories= $2.5

phone= $15

Step-by-step explanation:

Hi, we have to write a system of equations with the information given:

10p +26 ac =215

5p+ 21ac = 127.50

Where p is the number of phones sold and ac is the number of accessories sold.

If we multiply the second equation by 2 and subtract it to the first equation:

10p +26 ac =215

-

10p+ 42ac = 255

-16ac =-40

Solving for ac

ac = -40/-16

ac = 2.5

Replacing ac in any equation (first equation in this case)

10p +26 (2.5) =215

10p +65 =215

10p =215-65

10p = 150

p= 150/10

p= 15

so, converting firstly the mixed fractions to improper fractions and then "adding".
