Answer:


15x\leq 125

8 calculators at most.

Explanation:

Let x represent number of calculators.

We have been given that each calculator costs $15. So the cost of x calculators would be
15x dollars.

Since the order must be less than $125 in order to not go over budget, so cost of x calculators should be less than or equal to 125. We can represent this information in an inequality as:


15x\leq 125

Therefore, our required inequality would be
15x\leq 125.

Let us divide both sides of inequality by 15 as:


(15x)/(15)\leq (125)/(15)


x\leq8.3333

Since we cannot order 0.33 of a calculator, therefore, the math club can order 8 calculators at most.
