Ok so, here goes:
simple interest: r- rate, A- amount in the end, t- time, P- principal
<span>r = (1/t)(A/P - 1)
</span>Putting in our numbers
r = (1/4)((21236/5309) - 1) = 0.75
r = 0.75
Converting r decimal to R a percentage
R = 0.75 * 100 = 75%/year
The interest rate required to get a total amount, principal plus interest, of $21,236.00 from simple interest on a principal of $5,309.00 over 4 years is 75% per year.
Answer: The Answer is d
Step-by-step explanation: if you put the point on the line you will see they line up
Answer: (7 + d) 4 and 4 (7 + d)
Step-by-step explanation:
<em>4 (d + 7) = 4d + 28</em>
<em />
(7 + d) 4 = 28 + 4d (flipped version of 4d + 28)
4 (7 + d) = 28 + 4d (the same)
