The school purchased baseball equipment and uniforms for a total cost of $1762.the equipment costs $598 and the uniforms were $24.25 each. how many uniforms did the school purchase?

Since you know how much was spent on the equipment ($598.00) subtract that from the total (1762-598=1164) now you know how much money was spent on the uniforms so you divide the remainder of the money by the price of each uniform (1164 / 24.25=48) so 48 uniforms were purchased.
 
Hopes this helps you out =)
