Answer:
10$ per hour
Step-by-step explanation:
if she spended 120$ and had 180$ left, that means she had 300$ in the first place. of she works 30 hours, that means:
300 (the money she has)
÷ 30 ( her work hours )
When we divide this, the answer is ten. that is why she earns 10$ per hour
F(x) = 1.50x + 12.50
f(18) = 1.50(18) + 12.50
f(18) = 27 + 12.50
f(18) = 39.50 ....this is the amount Kelsey paid for 18 movies in 1 month
Answer:
-3x - 1
Step-by-step explanation:
(6x + 2)-(9x + 3)
We Begin by opening the brackets.
6x + 2 -9x - 3
Please note the change in the signs.
6x - 9x + 2 - 3
-3x - 1
The value of the quantity after 99 months is 5228.58.
Given that, an initial value = 5900, rate of decay = 0.85% and time period = 7 years.
<h3>What is the exponential decay?</h3>
The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.
The exponential decay formula formula is 
Here, the value 
= 5900×
= 5900×0.8862
= 5228.58
Therefore, the value of the quantity after 99 months is 5228.58.
