Answer:
D
Step-by-step explanation:
Growth rate is exponential, and rate is 100%
The answer of this functional mathematical equation problem happens to be 1/18
Amount paid for the first book is $17.
Amount paid for the second book is 0.75 x 8 = $6
Total amount paid = $17 + $6 = $23
Total full cost of the two books = $17 + $8 = $25
Amount of discount = $25 - $23 = $2
% reduction =

Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%
well from my understanding of the problem and calculations i would say.. (-5.5,0)
