<h3>What is division?</h3>

The division is one of the most basic arithmetical operators. When we divide a number (P) by another number(q), then it tells us how many times the other number(q) must be added to itself to form the first number(P).

It is given that the cost of tuition for the two years is $12,000, while the financial aid that Alejandro is eligible for is $7500, therefore, the amount that he will not be able to pay with his scholarship(financial aid) will be the difference in the fees of the student and the financial aid he is getting.

Difference = Two-year tuition fees - Financial Aid

= $12,000 - $7,500

= $4,500

Now, since Alejandro needs to save for a year so the sum he saves is $4500 therefore, the amount he needs to save each month can be written as,

$\text{Amount Alehjandro needs to save each moth}=\dfrac{\text{Amount that Alejandro need to save}}{\text{Number of months he needs to save}}$

$\text{Amount Alehjandro needs to save each moth}=\dfrac{4500}{12} = \$375$

Hence, the amount that Alejandro need to save for each of the month so that he can pay his tuition fee is $375.
