The answer to problem 14 is the equation c = 3i/e
To get this answer, you multiply both sides by 3 to undo the division of 3. Also, you divide both sides by 'e' to undo the multiplication of 'e'.
So it would look something like this
i = ec/3
3*i = 3*ec/3 ... multiply both sides by 3
3*i = ec
ec = 3i
ec/e = 3i/e ... divide both sides by e
c = 3i/e
==============================================
Problem 15)
P = 2L + 2W
2L + 2W = P
2L + 2W-2L = P-2L ... subtract 2L from both sides
2W = P-2L
2W/2 = (P-2L)/2 ... divide both sides by 2
W = (P-2L)/2
So the final answer is W = (P-2L)/2
Answer:
Roughly 2,000 times

Answer:
182,427.03
Step-by-step explanation:
total cost = r*p*n
---------------
1- (1+r) ^-n
Where r is the loan rate, p is the principal, n is the number of payments
rate = 4.04% / 12 months
total cost = (.0404/12)* 125000* 240
------------------------------
1- (1+.0404/12)^-240
101000
-----------------
1-.44635
101000
-----------------
.55364
182,427.03
Using Payments are 730 *240 months
730*240 =175200
16 and 26 and 36 because each time you need to add 10
