C. 7k^3 - k^2 - 3k + 16
Answer: $14.4
Step-by-step explanation:
To calculate the tip, you need to multiply the bill times .2. So 72x .2 = 14.4
Your max amount for this is $20. Let's say x represents the number of gallons.
20 ≥ 3.2x
x = 6.25 gallons
If they're asking for integers or whole numbers, you'd round down to 6 because you only have enough money for 6 full gallons. If you rounded up to 7, you wouldn't be able to fill it up completely because then you'd be over your $20.00 budget for gas.
