Answer: D
Explain: The one described was B, but the one that changes LESS is D
We have been given that Bobby's investment of $225,000 loses value at a rate of 3% per year. We are asked to find the value of the investment after 10 years.
We will us exponential decay function to solve our given problem.
We know that an exponential function is in form 
, where,
y = Final amount,
a = Initial amount,
r = Decay rate in decimal form,
x = Time.
Let us convert 3% into decimal.
Upon substituting 
, 
and 
, we will get:
Upon rounding to nearest dollar, we will get;
Therefore, the value of the investment after 10 years would be 
.
Answer:
Hours Charge
1 y = 6.5(1) + 5 = $11.5
2 y = 6.5(2) + 5 = $18
3 y = 6.5(3) + 5 = $24.5
4 y = 6.5(4) + 5 = $31
Step-by-step explanation:
In an equation y=mx+b, we can interpret the intercept b as the value of the initial charge and the slope m as the additional charge per hour. So, we can formulate the following equation:
y = 6.5x + 5
Where x is the hours and y are the charges for the babysitting, so, we can fill the table as:
Hours Charge
1 y = 6.5(1) + 5 = $11.5
2 y = 6.5(2) + 5 = $18
3 y = 6.5(3) + 5 = $24.5
4 y = 6.5(4) + 5 = $31
