number - N
The sum of a number and three more than twice that number is 27.
N + (2N + 3) = 27
what is the smaller number ?
N + 2N + 3 = 27
3N = 27 - 3
3N = 24
N = 8
Check
N + (2N + 3) = 27 = 8 + (2x8 + 3) = 8 + 16 + 3 = 27
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.
