Answer:

Let p be the number of phones sold and a be the number of accessory sold.

9p + 4a = 253

a - p = 8

Step-by-step explanation:

He gets $9 for every phone and $4 for every accessory, so you can write this as

9p + 4a

Then he made a total of $253 do the new equation is

9p + 4a = 253

We are also given that he sold 8 more accessories than phones. So we can write this as

a = p + 8

rearrange that so that all the variables are to one side.

a - p = 8

Now you have the two equations needed to solve the for the variable. The question didn't ask me to solve for the variable so I'll leave it here.

Jose sold 17 phones and 25 accessories.

Let x represent the number of phone sold and y represent the number of accessory sold.

Jose made a total of $253 in commission, hence:

9x + 4y = 253   (1)

He sold 8 more accessories than phones, hence:

y = x + 8

-x + y = 8   (2)

Solving equations 1 and 2 simultaneously gives:

x = 17, y = 25

Therefore Jose sold 17 phones and 25 accessories.
