Answer:
180%
Step-by-step explanation:
Set up an equation:
Variable x = percent of markup
102.56/56.98 = x/100
Cross multiply
102.56 × 100 = 56.98 × x
10,256 = 56.98x
Divide both sides by 56.98:
179.99297.... = x
Round to nearest whole number:
180 = x
Check your work:
56.98 × 180%
Convert the percentage into a decimal:
56.98 × 1.80
102.564
Round to nearest cent:
102.56
Correct!
You can use this equation to help you: (ab)^2 = a^2 b^2. And also (a^m)^n = a^m*n
So, here it is:
(7ab^3)^2 = 7^2 a^2 b^3*2 = 49a^2b^6
The correct answer is the third one - 49 a^2 b^6.
