Answer:

Step-by-step explanation:






Answer:
- 5.9%
Step-by-step explanation:
Data provided in the question :
Future value of the amount invested = $4,600
Principle i.e amount of purchase = $7,500
Time, n = 8 years
Now,
let the interest rate be 'i'
using compounding
$4,600 = $7,500 × (1 + i)⁸
or
0.613 = (1 + i)⁸
or
1 + i = 0.941
or
i = -0.059
or
interest rate = - 5.9%
Here negative sign means loss
9 - a (c + 5)
9 - 3 * 4
9 - 12
solution is -3
Cost of tablet $315
monthly payments of $25
a. 315 - 25 = $290
b. After each payment, the amount owed decreases. Therefore, the balance decreases.
second part of this: write equation for calculating the amount owed a for any number of payments n $ $25(n-1) =a
I cant draw a graph on here for you, but as n increases, then a decreases
d. as n increases by 1, how does a change? Answer: A decreases by $25 each time n increases by one
e. He will need to make 12.6 payments
The answer is the second one
