Plane A has just 1 ton of fuel left and has requested plane B to refuel it. Plane B has 21 tons of fuel. Fuel transfer happens a
t the rate of 1 ton per minute. Use this information as you work through the activity and find how long it will take to refuel plane A until both planes have the same amount of fuel. Let x be the time in minutes and y be the amount of fuel in tons. The equation y=x+1 represents the quality of fuel with respect to time in plane A, and y=-x+21 represents the quality of fuel with respect to time in plane B. For each equation, find two points that satisfy the equation.

For this case we have a function of the form:
Where,
A: initial amount
b: decrease rate
x: time in years
Substituting values we have:
For 2010 we have:
Answer:
an exponential decay function to model this situation is:
y = 1300 * (0.97) ^ x
The population in 2010 is:
y = 1083
A: initial amount
b: decrease rate

<h2>Answer:</h2>
The correct options are:
Choice A
Choice C
and Choice E
<h2>Step-by-step explanation:</h2>We are asked to find the value of:
60% of 94
We know that: it is represented as:
Choice A)
We know that:
could also be written as:
Since we multiplied and divide by 10 such that:
Hence, option: A is correct.
Choice B)
This option is incorrect.
Since by choice A we get that the correct expression is:
Choice C)
We get:
This option is correct.
Since,
Choice D)
This option is incorrect because the actual expression is:
Choice E)
[/tex]\dfrac{60}{100}\cdot 94[tex]
This is the correct expression.
