Answer:
Step-by-step explanation:
Let x represent the number of phones sold.
Let y represent the number of accessories sold.
Jose earns a $9 commission for every phone he sells. This means that the total commission earned for selling x phones would be
$9x
He also earns a $4 commission for every accessory he sells. This means that the total commission earned for selling y accessories would be
$4y
On a given day, Jose made a total of $253 in commission and sold 8 more accessories than phones. The equation would be
9x + 4y = 253 - - - - - - - - -1
Since he sold 8 more accessories than phones, it means that
x = y - 8 - - - - - - - - - - - -2
Therefore, equations 1 and 2 can be used to determine the number of phones sold and the number of accessories sold.
