Answer:
$4080
Step-by-step explanation:
We have the amount she will pay back, but first, we need to find the Interest accrued.
Simple Interest is given as:

where P = principal
R = rate
T = time taken (in years)
Therefore, the interest on $3,000 at 9% simple interest for 4 years is:

I = $1080
Therefore, the amount she will pay back is:
$3000 + $1080 = $4080

Explanation: x will be the number of sales the sales man had. so this is the equation 65x = 40 +300
65x -40x = 25x
25x = 300 then divide by 25
25 25
x = 12
Answer:
<h2>The range: {0, 10, 42}</h2>
Step-by-step explanation:
Put the values of x from the domain to the equation of the function
f(x) = 2x² - 8
for x = -2
f(-2) = 2(-2)² - 8 = 2(4) - 8 = 8 - 8 = 0
for x = 3
f(3) = 2(3)² - 8 = 2(9) - 8 = 18 - 8 = 10
for x = 5
f(5) = 2(5)² - 8 = 2(25) - 8 = 50 - 8 = 42
