Answer:
n/4 - 3 OR 1/4n - 3
Step-by-step explanation:
First, let's assign a variable to Emily's number. Let is be <em>x</em>.
Now all we have to do is go through the problem step by step.
"She finds 1/4 of the number..."
There are two ways you can do this. You can either multiply n by 1/4 (1/4n), or you can divide by 4 (dividing by four is the same as finding 1/4 of a number). For this example let's divide by four
n/4
"...and then subtracts 3."
All we have to do is subtract 3 from n/4
n/4 - 3
REMEMBER: like I said, there are two possible options. You can either have n/4 or 1/4n. They mean the same thing
Answer:
$27428.57
Step-by-step explanation:
To solve this problem, we can use the formula for compound interest:
P = Po * (1 + r)^(t)
Where P is the final value, Po is the inicial value, r is the rate of interest, t is the time.
With r = 0.06, t = 4 (The rate is for every 15 days, and the time is 2 months, so we have that 2 months = 4 periods of 15 days) and P = Po + 7200, we have:
Po + 7200 = Po * (1 + 0.06)^4
Po + 7200 = Po * 1.2625
Po * 0.2625 = 7200
Po = 7200 / 0.2625 = $27428.57
