Ryan a consumer electronics salesperson, earns a base salary of $1700 per month and a commission of 8% on the amount of sales he makes. One month Ryan received a $2244 paycheck. Find the amount of his sales for the month

This is the concept of algebra, let the total amount of sales be x:

Total income=[base salary]+[commissions]

base salary=$1700

commissions=8/100*x=0.08x

hence:

2240=0.08x+1700

solving for x we get:

540=0.08

x=540/0.08

x=$6750

We conclude that the total sales was $6750
