Answer:
You should have $1,463.95
Step-by-step explanation:
The formula for this is A=P(1+r)^x
P being the initial amount, r being the percentage, and x being the time passing.
<u>1. Write out the equation:</u> A=1400(1+0.015)^3
REMEMBER- writing percentages into decimals is moving the decimal point two times to the left--or dividing by 100!
<u>2. Parentheses:</u> 1400(1.015)^3
At this point, you're going to want to do exponents first (PEMDAS). If you're typing this into a calculator it should just give you the answer right away with the full equation.
<u>3. Answer:</u> 1463.95 (rounded to the nearest hundredth).
**I apologize if this is wrong; I haven't done it in a while so I don't know if I did 3 years or 3 months.. lol. That's probably not helping with the confidence level, but good luck!

Answer:
4.8 hours
Step-by-step explanation:
6 hours = 360 minutes (6x60)
360/5 = 72 (minutes per person worked)
72/2= 36 (person working at half productivity)
36x 8= 288 (total minutes of 8 people working at half productivity)
288/60= 4.8 (cover minutes back to hours)
Answer:
Downloading 28 songs will cost $26.64.
Step-by-step explanation:
Given that a brand-new music service is offering specials on individual song downloads, and the cost is $ 0.74 for each song up to 20 songs per month, and the cost doubles to $ 1.48 per download for any number of downloads over 20, to determine how much would it cost to download 28 songs the following calculation should be performed:
(20 x 0.74) + (8 x 1.48) = X
14.8 + 11.84 = X
26.64 = X
Therefore, downloading 28 songs will cost $ 26.64.
To solve this, we first have to find an individual rate:
3/5
4/7
For the first one:
1 lap in 5/3 minutes
Second one:
1 lap in 7/4 minutes
find a common LCD
5/3 and 7/4
20/12 and 21/12
4 laps in 7 minutes is faster
