Step-by-step explanation:
The answer is he will make $300 commission for 25 TV sets sold. The first thing you need to do is find out how much commission he makes on each TV. So we take $120 and divide by 10% and that gives us $12. So $12 is the amount of commission per TV. Then we just need to multiply the $12 by 25 TV sets. That gives us the answer of $300 commission total.
A second way to solve this problem is by taking the $120 and multiplying that by the 25 TV sets. That gives you $3,000 total for the 25 TV sets. Then you just divide the 10% commission Mike will make. That also gives you the answer of $300 commission.
The formula for the sum of n terms in an arithmetic progression is:
S = n/2 * (2a + (n-1)d)
Here, the common difference, d, is 8 and the first term, a, is 1. Substituting these into the formula, we get:
S = n/2 * (2*1 + 8(n - 1))
S = n + 4n² - 4n
S = 4n² - 3n
The answer is A.
