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.

Answer:
<em>Proof in the explanation</em>
Step-by-step explanation:
<u>Trigonometric Equalities</u>
Those are expressions involving trigonometric functions which must be proven, generally working on only one side of the equality
For this particular equality, we'll use the following equation
The equality we want to prove is
Let's set the following variables:
And modify the first variable:
Now with the second variable
Knowing that
We compute the other two trigonometric functions of X and Y
Computing
Then
Now we replace all in the first equality:
Thus, proven
