Answer:

Write a ratio.

70 : 5

x : 1

To solve for x, cross multiply.

70 : 5x

Divide both sides by 5.

14 = x

45 million * $2^{4}$ = 45million * 16 = 720million

Or you can use
$y=Ae^{kt}$
A is equal to 45 million
To find the rate, k, we can plug in:
$90million=45million*e^{k*1}
$
$2=e^{k}$
$k=ln(2)$
$y=4.5*10^{7}*e^{t *ln2}$
Knowing that t = 4
$y = 4.5*10^{7}*e^{ln(2)*4}
$
$y = 720 million$

Step-by-step explanation:

$4(y - 3) = 13 \\ \\ \therefore \: 4y - 4 \times 3 = 13 \\ \\ \therefore \: 4y - 12 = 13\\ \\ \therefore \: 4y = 13 + 12 \\ \\ \therefore \: 4y = 25 \\ \\ \therefore \:y = \frac{25}{4} \\ \\ \therefore \:y = 6\frac{1}{4}$
