Make 27 into 3^3, then since the bases are the same, solve (x-1) = 3. The answer is 4.
First, minus salary
paycheck=comission+salary
paychec-salary=comision
6500-1000=5500
comission/sales=5500/45000=0.122222222/1
pecent means parts ou fo 100
x%=x/100
0.122222/1 times 100/100=12.2222/100=12.222%
about 12%
The answer will be 0.026666666666 or just put a little sgwigly line ~ kind of like that to show that the last number will go on and in forever hope this helps!! Ask me any other questions if you have any.
