Answer:
$81.60
Step-by-step explanation:
A 20% markdown means that the chairs were sold at 80% of the original cost.
Original cost = $102
markdown = 20%
Cost after markdown = original cost* (1-markdown)
Cost after markdown = 102 *(1 - 0.20)
= 102*0.80
= 81.6
Therefore, the 4 chairs were sold at a total cost of $81.60
Answer: No solution
Step-by-step explanation:
7(x+4) - 6(x+3) = x + 5
7x + 28 - 6x - 18 = x + 5 distributing
7x - 6x - x = -28 + 18 +5
0 = -5 <u>Not true</u>
No solution
Answer:
I believe the answer is 8.
If x is the number of sides of the regular polygon, then the sum of the interior angles is (x - 2) * 180 = 56 * 90. Solving for x gives 30 for the number of sides of the regular polygon.
To get the central angles measure, divide 360 by 30 to get 12 degrees for the measure of one of the 30 central angles.
Answer: 12 degrees
