Excellent!  Are you ready to check your child’s answer? Look below to see if their solution matches ours.

Lower Elementary:
Answer:   6 fish
Solution:  Chloe caught 6 + 4 + 1 = 11 fish in total. She threw 3 snappers back because half of 6 is 3, and she also threw 2 mackerels back because half of 4 is 2. That means she went home with 11 – 3 – 2 = 6 fish.

Upper Elementary:
Answer:   \$14.00
Solution:  Three tokens for the roller coaster cost 25¢ × 3 = 75¢. Five tokens for the Ferris wheel cost 25¢ × 5 = \$1.25. The total cost for 7 rides on the roller coaster cost \$0.75 × 7 = \$5.25, and 7 rides on the Ferris wheel cost \$1.25 × 7 = \$8.75. So, Landon spent \$5.25 + \$8.75 = \$14.00 on rides.

Middle School:
Answer:   12π inches
Solution:  The formula we use to find the circumference of a circle is C = πd, d being the diameter of the circle. The hamster runs π × 6 = 6π inches. The guinea pig runs π × 18 = 18π. So, the guinea pig runs 18π – 6π = 12π inches farther than the hamster.

Algebra and Up:
Answer:   \$25.24
Solution:  To find the price of the rentals, we can use the expression C = \$20.00 + \$1.50t + \$2.98g wherein C is the total cost of the rental, t is the number of hours spent with the jet skis, and g is the gallons of gas used. James rented 1 jet ski for 2 hours and used 0.75 gallons of gas, so he spent \$20.00 + \$1.50 × 2 + \$2.98 × 0.75 = \$25.24 after rounding.
