All you have to do is to look at the numbers in the queston and then etired add subtrack or multiply so in this question the numbers are 325$and 6.5%and $4,800 so this is a two step problem first you go to multiply 4,800 and 325 which equal 1560 and then add 6.5% and 1560 which equal 101.4 so she will make 101.4 in a work week
So her NORMAL salary is $325, and if she sells anything, she gets 6.5% of the money of what she sold. she sold $4,800 so u need 6.5% of that PLUS her regular salary of 325 so 4800*0.065=312. 312+325=$637 she got $637
