Julie has been offered two jobs. The 1st one pays $400 per week. The 2nd job pays $175 per week plus 15% commision of her sales. How much will she have to sell i n order for the 2nd job to pay as much as the first? how do you do this? i don't know the steps to.

400  175 = 225
0.15x = 225
x = 225/0.15
x = 1500 
thanks

You're welcome.

job1 = 400
job2 = 175 + .15s , where s is sales
when are they equal?
175 + .15s = 400
.15s = 225
s = 225/.15 = 1500
notice the solution to the equation contains all the calculations that Ms Sue has also given you.
