The worth of Sarah's investment when she is 68 is $14,728.51.
<h3>What is the worth of the investment?</h3>
The formula that can be used to determine the worth of the investment is:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years = 68 - 18 = 50
$500 x (1.07)^50 = $14,728.51

35%.
42/120 = 0.35.
0.35 X 100 = 35. That tells us 42 is 35% of 120.
Answer:
It's f(x)=10x+8
Step-by-step explanation:
Because it says every hour not every half hour and the graph changes by 0.5 instead of 1 so m would equal 10
When x = 5. Plug in 5 for x
f(5) = -5(5) - 4
Remember to follow PEMDAS. First, multiply -5 with 5
-5 x 5 = -25
Next, subtract 4
f(5) = -25 - 4
f(5) = -29
B. f(5) = −29 is your answer
hope this helps
