Answer:
0.75m + 4 [tex]\leq[/tex] 10, Nick doesn't have enough money for a 15 minutes car wash.
Step-by-step explanation:
They charge you $4 for the first 5 minutes so you're going to add that into your equation.
They charge you $0.75 for each minute after those 5 minutes, you don't know how many minutes you'll spend so m, the number of minutes is unknown
Now onto the car guy, he says you should at least spend 15 minutes for a car wash. Now multiply 0.75 x 15. You'll get 11.25. Add the 4 and overall you have 15.25. That is NOT less than NOR equal to 10 so therefore he doesn't have enough money. Anything more than 8 minutes is gonna be over $10.
Hope that helps!
