Answer:
He receives $476 in comission.
Step-by-step explanation:
This question can be solved using a rule of three.
$6,800 is 100% = 1. x, which is his commision, is 7% = 0.07. Then
6800 - 1
x - 0.07
x = 6800*0.07
x = 476
He receives $476 in comission.
To practice, what if the two are added now? lets add one term at a time. first the x terms. 3x+x= 4x. then y+-3y=-2y. finally 3+-2=1. now putting them together we get 4x-2y=1.
multiplying the first equation by 3 gets us 9x+3y=9. basically multiplying each term by 3. now just do the same thing from the first part, so start with the new 9x+x and continue
So he invests 3,250 dollars for year!
Interest: 3,250 x 0.06 = $195
Per Year: 3,250 + 195 = 3,445 dollars anually
3 Years: 3,445 x 3 = $10,335
The answer to the question is 33%. Hope this helps!
