First, figure out the percentage of students that said math is their favorite subject in the 80 student sample.
\frac{24}{80}  \times  \frac{x}{100}  \\ 80x = 2400 \\ x = 30 \\ 30\%
Now, we multiply 300 by .3 to approximate how many students would choose math as their favorite subject
300 \times .3 = 90
Estimating, 90 students would choose math as their favorite subject going off of the given data.

Okay so to start this problem we will calculate the amount due after the first month.
$1,200 x .145 = 174 <--- This is going to be the applied interest for the first and second payment.
Add 1,200 + 174 = 1374 

Now, going into the second month the total amount left should be 2,187.90 because 3,387.90 - 1,200 = 2,187.90

We are going to have to take 1,200 for the second monthly payment. So now the total left to pay should be $987.90.

Let us calculate the actual amount of the second payment now. The added interest rate is going to be the same as the first month so once again we will pay $1374.00 this month.
The new amount paid = 1374+1374 = $2748.00

So we are going to setting up a new equation for this month since we don't have $1,200 to calculate with.

The new total due is 987.90. 987.90 x .145 = $<span>143.25
</span>So, 987.90 + 143.25 = $<span>1,131.15
</span>We are going to add up all the monthly payments with interest to calculate the total cost.
$2748.00 + 1,131.15 = $<span>3879.15
</span>
It takes 3 months to pay off the card.
The total amount paid is $<span>3879.15.
</span>
I hope this helped!
