Variable

• x: number of three-credit courses

Given that 1 three-credit course costs $375 for tuition, fees, and books; then x courses will cost 375x dollars.

On the other hand, the college charges a $300 fee.

Combining these two amounts, the total cost is 300 + 375x dollars.

This total cost must be at most equal to $1500 (his budget). Mathematically:


\begin{gathered} 300+375x\le1500 \\ \text{ Subtracting 300 at each side of the inequality:} \\ 300+375x-300\le1500-300 \\ 375x\le1200 \\ \text{ Dividing by 375 at each side of the inequality:} \\ (375x)/(375)\le(1200)/(375) \\ x\le3.2 \end{gathered}
