Answer:
4.75%
Step-by-step explanation:
When simple interest is charged, the payback amount is ...
A = P(1 +rt) . . . . for annual rate r and a term of t years
Using the given values, we can solve for r.
10280 = 8000(1 +6r)
1.285 = 1 +6r . . . . . . . . divide by 8000
0.285 = 6r . . . . . . . . . . subtract 1
0.285/6 = r = 0.0475 = 4.75% . . . . . . divide by 6; express as %
Theo paid interest at the rate of 4.75%.
Answer:
c=35
Step-by-step explanation:
c=180-d
c=180-145
c=35
The answer to that is: X = 8.
40 divided by 5 = 8.
To check we can do 5 x 8 = 40.
X = 8
Answer:
cumulative cell phone cost after 18 months = 922.4
Step-by-step explanation:
We are given the line of best fit for the data as;
C = 51m + 4.4
where;
C is the cumulative cell phone cost
m is the number of months.
Now, we are told that m = 18 months
Thus;
C = 51(18) + 4.4
C = 918 + 4.4
C = 922.4
