Mr. trager has $500.00 to spend at a bicycle store. all prices listed below include tax.
42
• he buys a new bicycle for $273.98.
• he buys 3 bicycle reflectors for $7.23 each and 1 bicycle helmet for $42.36.
• he plans to use the remaining money to buy new cycling outfits
for $78.12 each.

The inequality would be 273.98+(7.23*3)+42.36+78.12x which is less than or equal to 500. Now solve it. Think that the less than or equal to sign is a regular equal sign. Solve the inequality like a normal equation. When you solve it, you get 1. something. Just round it to 2 costumes.

Hope that helps!!
