Given:
Fernell's speed 
mph
Dabney's speed 
mph
Denote:
- distance covered by Fernell
- distance covered by Dabney
- Fernell's time
- Dabney's time
1. If Fernell drove for 3 hours longer than Dabney, then his time is 3 hours more than Dabney's time and

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).
