We have a question: A vegan restaurant serves three kinds of protein: seitan, beans, and lentils. There are ten dishes on their menu. Two have beans and lentils, and two have beans and seitan. The remaining dishes only have one kind of protein in them. Half of the remaining dishes have only beans, and there are three times as many dishes with only beans as with only seitan. How many dishes include lentils?
And an answer: 4
So how you got the answer?
The vegan restaurant serves 10 - 2 - 2 = 6 dishes with only one kind of protein. There are 6 / 2 = 3 dishes with only beans. There is 3 / 3 = 1 dish with only seitan. Thus, there are 6 - 3 - 1 = 2 dishes with only lentils. There are also 2 dishes with beans and lentils, so there are 2 + 2 = 4 dishes that include lentils.

We have a question: Dennis wants to buy 4 pairs of pants from the store which cost $110.00 each with a 30% discount and he also wants to buy 2 pairs of socks which cost $60.00 with a 30% discount. How much money will Dennis have to spend in total after he bought all the items he wants after the discount?
And an answer: 392
So how you got the answer?
Dennis wants to buy 4 pairs of pants which cost 110x4 = $440. And he also wants to buy 2 pairs of socks that cost 60x2 = $120. The total amount he needs to spend without the discount is 440 + 120 = $560. The discount he will have amounts to $560x.0.30 = $168.00. So the total amount he needs to spend after deducting the discount from the total amount is 560 - 168 = $392.

We have a question: On a road map, 1/4 inch represents 8 miles of actual road distance. The towns of Pence and Hillcrest are represented by points 3 3/8 inches apart on the map. What is the actual distance, in miles, between the towns?
And an answer: 108
So how you got the answer?
If 1 / 4 inch on the map represents 8 miles on real land, 1 inch represents 4 * 8 = 32 miles. Since 1 inch represents 32 miles, 3 inches represent 3 * 32 = 96 miles. 1 / 4 inch represents 8 miles, 1 / 8 inch represents 8 / 2 = 4 miles because 1 / 8 is half of 1 / 4. If 1 / 8 inch represents 4 miles, 3 / 8 of an inch represents 3 * 4 = 12 miles. This means 3 3 / 8 inches on the map translate to 96 + 12 = 108 miles.
