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
100-20 = 70% = .7
364/.7 = 520
It was worth $520 last year
Answer:
Convert Equation 1 to slope-intercept form.

, therefore they are perpendicular and there is no solution to this linear system. The two lines have no points in common.
