Answer:
b = 3/4
Step-by-step explanation:
Hi!!!
You want the value of B. To get that, we have to divide both sides by 16:
Thus the answer to your question is .
<u>Check:</u>
3/4 * 16 = 3 * 4 = 12.
12 = 12
So we are correct!!!
Using an exponential equation, supposing a rate of 5%, it is found that it will take about 2.9 years for Emma's balance to reach $450.
An increasing exponential function is modeled by:
In which:
A(0) is the initial value.
r is the growth rate, as a decimal.
In this problem:
Her initial balance is of $300, hence . A(0)=300
The growth rate is of 15%, hence R =0.15
Then,
It will reach $450 after t years, for which A(t) = 450, hence:
It will take about 2.9 years for Emma's balance to reach $450
