So it is basically extended by 75%. 25% of 3.5 is 0.875. 0.875 times 3 is 2.625. That is 3/4 of the segment. Now you have to add it to the 3.5. Your final answer would be 6.125.
1 liter=.26 gallons so 20 liters= 20*.26= 5.2 gallons.
You need to use .75 ounces of soda ash per gallon so you must multiply .75 by 5.2.
.75*5.2 = 3.9 ounces

Let w be the number of weeks. He withdraws $25 per week, so in w weeks, he withdraws 25w. He starts with $500, so after w weeks he has 500 - 25w. He wants this amount to be at least $200. "At least" means "greater than or equal to."
500 - 25w >= 200
-25w >= -300
w <= 12
Answer: Keith can withdraw $25 per week for at most 12 weeks.
