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.
Answer:
x= 7
Step-by-step explanation:
5x-11=24
+11 +11
5x = 35 35/5 = 7 x=7
5(7) - 11 = 24
35 - 11 = 24

Answer:
Step-by-step explanation:
Let the required amount is x.
<u>Alcohol content is same at the end:</u>
- x*0.17 + 4*0.2 = (x + 4)*0.19
- 0.17x + 0.8 = 0.19x + 0.72
- 0.19x - 0.17x = 0.8 - 0.72
- 0.02x = 0.08
- x = 0.08/0.02
- x = 4
