Jesse is a bartender at a local pub. On Friday, he made $27.40 in tips; on Saturday, he made $34.70 in tips; and on Sunday, he made $7 less than he made on Friday. How much did Jesse earn in tips during the three days?
Pretty straightforward. Jesse made $27.40 + $34.70 + ($27.40 – $7) = $82.50 in tips.
Rob “Speedy Gonzalez” Barton ran 1.5 miles in 9:57. The next day, he ran it in 10:02. On the third day, he ran it in 10:07. What is his average time for the 1.5-mile run?
First, convert all the times into seconds, just to make the math a little easier:
9:57 = (9 × 60) + 57 = 597 seconds
10:02 = (10 × 60) + 2 = 602 seconds
10:07 = (10 × 60) + 7 = 607 seconds
Add the seconds together: 597 + 602 + 607 = 1,806 seconds. Now, divide by the number of times Rob ran the 1.5-mile run (three times) to discover that his average speed is 1,806 ÷ 3 = 602 seconds. Finally, convert the seconds to minutes by dividing by 60: 602 ÷ 60 = 10 minutes, with 2 seconds left over. Rob’s average time for the 1.5-mile run is 10:02.
The sum of two consecutive odd positive numbers is 112. What are the numbers?
Sum means addition. Let n = the first number. That means that n + 2 = the second number (because they’re consecutive odd numbers). Here’s your equation:
n + (n + 2) = 112
Solve for n:
The first number is 55. The second number is 55 + 2 = 57.
