Answer:
A. $58.50
B. $80
C. No. The markup was 33 1/3%
Step-by-step explanation:
You are expected to know the relevant relationship is ...
cost + markup = selling price . . . . also called "store price" in this problem
___
A. The markup is 30% × $45 = $13.50, so the store price is ...
$45 + 13.50 = $58.50
___
B. When the 30% markup is added to the 100% cost, the selling price is 130% of the cost, or 1.30 times the cost. Here you have ...
$104 = 1.30 × cost
$104/1.3 = cost = $80 . . . . . divide by the coefficient of cost
___
C. The markup is $100 -75 = $25, so the markup percentage based on cost is ...
$25/$75 × 100% = 33 1/3%
This is not 30%.

Step-by-step explanation:
Answer:
Choice B) {-21, -7, 7, 21}
Step-by-step explanation:
The multiples of 7 are: 0, 7, 14, 21, 28, 35, ... both the positive and negative versions of each number. Erase the even numbers in that list to end up with 7, 21, 35, ...
Choice A fits the description, but there are items missing, namely -7 and 7. So this answer choice is crossed off the list
Choice B has both odd numbers and multiples of 7 listed. Every number is listed. This is why this is the answer.
Choice C has multiples of 7, but these are even numbers. We can cross it off the list.
Choice D is a similar story to choice C, though it has some odd numbers in this list.
