Question

The math club is ordering calculators for club members. Each calculator costs $15. The order must be less than $125 in order to not go over budget. How many calculators can they order? Write an inequality to describe this scenario. Be sure to define your variable.

Answer 1

`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.
