Answer:
25f+100c<500
Step-by-step explanation:
He wants that total calorie count to be less than 500 cals, so we use <.
25f, means for each french fries we have 25 calrs.
100c, for each chicken wings we have 100 calories.
So inequality is 25f+100c<500.
For example, he can not eat 4 french fries and 4 wings (4*25+100*4=500 is not less from 500, it is equal), but he can eat 3 fries and 4 wings (3*25+100*4=475<500).
