Work shown above! Answer is the 3rd Choice!
So the ceiling takes 5/6 gallon to paint. We know that you already have 1/30 gallon and another gallon in addition to that. We must convert the 5/6 into ?/30 so we can see how much we need to use. So if we convert 5/6 to out of 30, we get 25/30. So the first can has 1/30 gallon so we subtract that amount from the total paint needed. So now we only need 24/30 gallon to paint the ceiling. If we subtract that amount needed from the full (30/30) can we have left, that will give us the remaining amount of paint we have left. 30/30-24/30= 6/30. This reduces to 1/5. So there is 1/5 gallon of paint left over after painting the ceiling.

I always had trouble doing percents, but my last algebra teacher taught me an easy way, where you turn the percent into a decimal.
Maria: to find 25% of 26.50, you multiply 26.50 by 0.25 to get 6.625. now, you subtract 6.625 from 26.50 to get 19.875. which would round to 19.88$. To find the 10% sales tax, you multiply 19.88 by 0.10 or 0.1 to get 1.988. that would round to 2.00. She would then add 19.88 and 2.00 to get 21.88$.
Edwin: I am not even sure how to figure out Edwin's math, his is not even comprehendible for me.
When I'm shopping, I always use Maria's method to figure out the price of things, therefore, I am 99% sure she is correct and Edwin is not. If it said that they both came with 23$, and the price of the book is now only 21.88, then yes, they have enough money to purchase the book.
and sorry this took long, I'm multitasking.
