Reasoning and answer: Since wants needs an 85 as an average and he takes five tests, he must have 85 * 5 = 425 total points. Currently he has 85 + 79 + 92 + 84 = 340 points. So for his fifth test he needs 425 - 340 = 85 points.
The answer: 85

First, we need to determine how much the entire meal costs before we can determine the tip. We perform 10 + 20 + 30 = 60 dollars worth of food. Now we need to find out how much the total tip to be paid is, by multiplying 60 * .2 = 12 dollars in tips. Since they want to split this evenly amongst three people, this works out to 12 / 3 = 4 dollars in tips per person.
The answer: 4
