Answer:
Sensational Rentals
Step-by-step explanation:
Mr Cool's Rentals-
432 minus 100 = 332
332 * 0.11 = 36.52
36.52 + 36.52 = 73.04 (because she's coming back you need to double it)
73.04 + 99 = 172.04
The cost will be $172.04 if she goes with Mr. Cool's rentals.
Sensational Rentals-
432 minus 150 = 282
282 * 0.15 = 42.3
42.3 + 42.3 = 84.6
84.6 + 75 = 159.6
The cost will be $159.6 if she goes with Sensational Rentals.
Therefore, because 172.04>159.6 Sensational Rentals will have the better deal.
It is 3.5, because anything inside an absolute is always positive.
The total number of parts to the paste is 4+3+2+1 = 10. Of those, 2 parts are resin. If the "parts" are equal weight, then 2/10 of the weight is resin.
One billboard requires 30 pounds of paste, so 4 billboards will require 4·30 = 120 pounds. If 2/10 of the paste is resin, then (2/10)·(120 pounds) of resin will be required, or 24 pounds of resin.
