John's cell phone gives him 1250 minutes for $25. He used 1300 minutes. How much will his cell phone company bill him for?

kondaur [170]

Answer:

$26.

Step-by-step explanation:

We have been given that John's cell phone gives him 1250 minutes for $25. We are asked to find John's bill for 1300 minutes.

First of all, we will find charges per minute by dividing $25 by 1250 as:

$\text{Charge per minute}=\frac{\$25}{1250}$

$\text{Charge per minute}=\$0.02$

Now, we will multiply 1300 by $0.02 to find John's bill.

$\text{John's bill}=\$0.02\times 1300$

$\text{John's bill}=\$26$

Therefore, John's company will charge him $26 for 1300 minutes.

What is the equation of the graph

balandron [24]

Answer:

y=6^x-2

Step-by-step explanation:

Start with the parent function, a^x. The graph looks like it has been translated b units down, so our function is a^x+b. Now at x=0, y=-2. So b=-2. Next at x=1, y=3. 3=a^(1)-2, a=6. y=6^x-2 is the equation
