Since they are the same variables
Answer:
3
Step-by-step explanation:
Those are factors of 9 not multiples
the blank is 162
since 81 and 81 are both perfect squares the middle term (blank) will be the product of their roots times 2
√81=9
√81 =9
9 x 9 x 2
= 162
So, the first 10 suits came with a commission of 5%, so for each suit it was:
250*5%
this is

but this counts for 10 suits, so together his commssion was 10*12.5=125 dollars
and the "extra" 3 suits came with a comittion of 5+3 percent, so 8 percent, which is

for each suit, and 60 in total.
his total comission was 125+60=185 dollars.
