profit = 129.63% (to the nearest hundredth) as a percent of the price the store paid for the book
Step-by-step explanation:
Use the percentage change formula:
percent change = [ (difference between the initial value and the final value) ÷ initial value] x 100
= [ (6.20 - 2.70) ÷ 2.70 ] x 100
= [ 3.5 ÷ 2.70 ] x 100
= 37/27 x 100
= 129.6296296...
= 129.63% (to the nearest hundredth)

Step-by-step explanation:
The union is the list of elements that are in either of the two sets.
F ∪ H = {c, d, e, f, g, h}
The intersection is the list of only those elements that appear in both sets. (There are none.)
F ∩ H = { } . . . . the empty set
The answer is C because "dropped" means minus so it is asking: 2-5 which should be -3 not -5.
