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.
Given equation:
P=1500 (1.04)^x
When have to find x, when population, p=1900
Put value of P=1900 in above equation.
1900=1500(1.04)^x
Divide both sides by 1500
19/15=(1.04)^x
1.27=(1.04)^x
Take natural log.
ln(1.27)= ln(1.04)^x
ln(1.27)=x ln (1.04)
Divide both sides by ln (1.04)
x=6 years
Answer: 6 years
I think 710 is the answer
266+266+89+89= 710
