Answer:
4
Step-by-step explanation:
It is asking you to substitute or plug in the values.
Example:
Evaluate 3r(s+3) if r = -3 and s = 5
See that r? It means that you put in -3 in place of the r, and you put 5 in place of the s so it looks like this:
3*-3(5+3)
Now solve that using order of operations and you should get
-9*(5+3) (don't forget that your'e distributing here FIRST then add)
-45+-27
-72
That's how you solve an expression like that. This is only an EXAMPLE. Hope it helped.
Answer:
$2.77
Step-by-step explanation:
Here's one way to do it.
Data:
We must express the interest rate on a monthly basis.
i = 7.5 %/yr = 0.625 %/mo = 0.006 25
A = $1300
n = 6 mo
A. Monthly payments
The formula for the monthly payment (P) on a loan of A dollars that is paid back in equal monthly payments over n months, at an annual interest rate of i % is
Calculation:




P = $221.43
B. Total amount paid over six months
Paid = 6 × 221.43
Paid = $1328.58
C. Amount paid after four months
Paid = 4 × 221.43
Paid = $885.72
D. Balance owed after four months
Owed = 1328.58 - 885.72
Owed = 1341.14 – 1121.08
Owed = $442.86
E. Interest included in Payment 5
I = Pi
I = 442.86 × 0.006 25
<em>I = $2.77
</em>
The interest included in Payment 5 is $2.77.
