Since 5, 4, and 2 share a factor of 2, we have to do 5*4*2/2 = 20
They will have to buy all three items again in 20 years

I hope this helps!
Thank you!!
An exponential function can either represent a growth or decay.
- The price of fuel A is increasing.
- Fuel B recorded a greater percentage change in price
<u>Part A</u>
For fuel A, the exponential function is given as:

An exponential function is represented as:

Where b represents the rate.
By comparison

Since b (i.e. 1.04) is greater than 1, then the price of fuel A is increasing.
<u>Part B</u>
The table represents an exponential function.
The rate of fuel B is calculated by dividing the current price by the immediate previous price.
So, we have:


By comparison, 1.06 is greater than 1.04 (the rate of fuel A).
Hence, fuel B recorded a greater percentage change in price

Answer:
The sum is 1
Step-by-step explanation:
When you add a negative number to a positive number, it is basically just subtracting the negative from the positive. To make it simple, 5 + -4 is just 5 - 4.
Hannah was wrong in saying you take the sign of the larger number because it would not matter if the first number was a million, the signs don't change based on the size of numbers.
