Answer:
0.75m + 4 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 <u>m,</u> 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!

Answer:
38
Step-by-step explanation:
40 x 95/100 = 38
95 is the amount
40 is the percent that this item is off by
100 is the maximum percent the item can be off by
Another example to prove this
40 percent * 95 =
(40:100)* 95 =
(40* 95):100 =
3800:100 = 38
