Answer:
Try taking a screen shot as this is indecipherable.
Step-by-step explanation:
The answer would be 71/6 or 11 5/6.
1 liter = 100 centiliter
0.31 * 100 = 31
31 centiliters = 0.31 liters
3z < 30 - 6
3z < 24
z< 24/3
z< 8
answer is z < 8
Take 20 and multiply it by .0475. After you get that answer, take it and add it to the 20 dollars. It might have decimals, it might not. Hope this can help!
