Answer:
C
Step-by-step explanation:
32 - 2 = 30
30 / 2 = 15
Answer: C (areas B and D)
Step-by-step explanation:
B is 27:36 = 9(3):9(4) = 3:4
D is 24:32 = 8(3):8(4) = 3:4

Look below for answer! Have a great day and please mark me brainliest!
Step-by-step explanation:
Bedroom 1: 22x15=330
330x7.25=2392.5
Bedroom 2: 15x12=180
180x7.25=1305
Bedroom 3: 13x12=156
156x7.25=1131
2392.5+1305+1131= 4828.5
Bedroom 1: 22x15=330
330x6.75=2227.5
Bedroom 2: 15x12=180
180x6.75=1215
Bedroom 3: 13x12=156
156x6.75=1053
2227.5+1215+1053+100= 4595.5
Therefore, 6.75 per square foot plus a $100 fixed installation fee would be the cheapest.

Here's the general formula for bacteria growth/decay problems
Af = Ai (e^kt)
where:
Af = Final amount
Ai = Initial amount
k = growth rate constant
<span>t = time
But there's another formula for a doubling problem.
</span>kt = ln(2)
So, Colby (1)
k1A = ln(2) / t
k1A = ln(2) / 2 = 0.34657 per hour.
So, Jaquan (2)
k2A = ln(2) / t
<span>k2A = ln(2) /3 = 0.23105 per hour.
</span>
We need to use the rate of Colby and Jaquan in order to get the final amount in 1 day or 24 hours.
Af1 = 50(e^0.34657(24))
Af1 = 204,800
Af2 = 204,800 = Ai2(e^0.23105(24))
<span>Af2 = 800</span>
