Question

Suppose your allowance is $2 now, and it will

Answer 1

An exponential expression to represent your allowance 20 weeks from now would be:

2^20

This is correct since we are basically multiply 2 by itself for twenty times.

Now, we solve it.

2^20 = 1048576

Thus, your allowance by the end of 20 weeks is $1,048,575.

You would be a millionaire by then.

Answer 2

Answer: f(x) = 2(2)ˣ

              f(20) = $2,097,152

Step-by-step explanation:

Use the exponential formula:  f(x) = a(b)ˣ   where

• a = initial (starting) amount
• b = rate
• x = time

Given: a = 2, b = 2

Equation: f(x) = 2(2)ˣ

                f(20) = 2(2)²⁰

                         = 2,097,152
