There would be 2034 students competing in 2012.

We can write a simple equation to find this answer. Let X, be the number of students starting in 2012. Then, we multiply by 0.9 and 1.1 to get to 2014. To work backwards, just divide by 1.1, then by 0.9.

2014 / 1.1 / 0.9 = 2034

$612.04 will Jack have to pay if he drives 1,248 miles in one particular month .

<u>Step-by-step explanation:</u>

Here we have , Jack’s new truck costs $325 per month for car payments. In addition, he estimates that gas and maintenance expenses cost $0.23 per mile. We need to find :

a. Express the monthly cost as a function of the miles driven.

Let number of miles driven be x , & monthly cost be y So , equation is :

⇒ $y=0.23x+325$ , Where 325 is Jack’s new truck costs $325 per month for car payments .

b. How much will Jack have to pay if he drives 1,248 miles in one particular month?

According to question we have ,

$x=1,248$

Putting value of x in $y=0.23x+325$ we get:

⇒ $y=0.23x+325$

⇒ $y=0.23(1248)+325$

⇒ $y=287.04+325$

⇒ $y=612.04\$

Therefore , $612.04 will Jack have to pay if he drives 1,248 miles in one particular month .
