y+20
Step-by-step explanation
240=12x+8y
Step 1: Flip the equation.
12x+8y=240
Step 2: Add -8y to both sides.
12x+8y+−8y=240+−8y
12x=−8y+240
Step 3: Divide both sides by 12.
12x

=
−8y+240

<h3><u>The function that represents the price P of the car after x years is:</u></h3>

<em><u>Solution:</u></em>
<em><u>The decreasing function is given as:</u></em>

Where,
y is future value
a is initial value
r is decreasing rate in decimal
t is time period
From given,
a = 25000

number of years = x
future value = P
Therefore,

Thus the function is found
Answer:

5 minutes.
Step-by-step explanation:
It is given that, Amelia can wash 8 plates in 24 minutes.
So, if this rate remains constant then 1 plate will be washed in
minutes.
Again, it is given that, Amelia bakes 12 cookies in 60 minutes.
So, if this rate also remains constant then she will bake 1 cookie in
minutes. ( Answer )
