B.143

step by step:
\frac{11}{12}  =  \frac{b}{156}
use cross multiplication
12 \times b = 11 \times 156
12b = 1716
divide both sides by 12
\frac{12b = 1716}{12}
b = 143

Answer:

B. 143

Step-by-step explanation:

11        b

----- = -------

12          156

using cross products

11 * 156 = 12 b

divide by 12

11 * 156/12 = b

11 * 13 = b

143 = b

The given formula is f(x) = 20(1.2)^x

The formula is the starting amount multiplied by 1 + the percentage raised to the number of weeks.


A) the percent increase is 20% ( 1.2 in the formula is 1 +20% as a decimal)

B) the original amount is $20

C) for 2 weeks, replace x with 2 and solve:

20(1.2)^2

20(1.44) = $28.80

After 2 weeks the coupon is $28.80

D)  To solve for the number of weeks (x) set the equation equal to $100:

100 = 20(1.2)^x

Divide both sides by 20:

5 = 1.2^x

Take the natural logarithm of both sides:

ln(5) = ln(1.2^x)

Use the logarithm rule to remove the exponent:

ln(5) = x ln(1.2)

Divide both sides by ln(1.2)

x = ln(5) / ln(1.2)

Divide:

X = 8.83

At 8.83 weeks the coupon would be $100, so after 9 weeks the coupon would be greater than $100

The answer is 9 weeks.
