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.
Answer:
10/25%
Step-by-step explanation:
Answer:
If using simple interest, the formula is:
= Amount * ( 1 + rate * time)
= 20,000 * ( 1 + 4% * 5)
= $24,000
Interest = Balance after 5 years - Investment
= 24,000 - 20,000
= $4,000
Using Compound Interest:
= Amount * ( 1 + rate)^time
= 20,000 * ( 1 + 4%)⁵
= $24,333.06
Interest = 24,333.06 - 20,000
= $4,333.06
