Answer:
CI=P*(1 + R/100)^18
A=(CI + P) = P(1+R/100)^18
13500/P=1(100+R/100)^18
A/P=(100+R/100)^18
A/P=(100+R/100)^18
A=13500$ as (750 * 18)
(13500)/P=(1 +1.15/100)18
(13500)/P=(1+1.15/100)18
13500=((1.0115)^18
P=R$10989.02
Step-by-step explanation:
CI=Compound Interest
A=Amount
P=Principal.
V=PiR^2H/3
Pi = 3.14 (use pi symbol on calculator)
R is the radius if the cones bottom
H is the height of the cone
Facts:
- tub has 1400 gallons
- draining at 27 gallons/minute
How much water will be left after 18 minutes?
We know that after 1 minute, there will be 27 gallons less.
So after 18 minutes, there must be 18 times less water.
27 x 18 = 486
This is how much water was lost in 18 min
So to find out how much he had left after <u>486 is subtracted.</u>
Therefore, the answer is A) -486 gallons
