• $30.59

• $32.59

• $34.59

• $36.59

Answer explanation

Mauricio spent $1.99 x 4 = $7.96 on chips and $5.45 on cola, totaling $7.96 + $5.45 = $13.41. He paid with $50, so his change is $50 - $13.41 = $36.59, which is the correct answer.

At the start of Myka’s hike, the temperature was 68°F. As she hiked, the temperature dropped 5.4°F for every 1,000 feet she hiked up in elevation. What was the temperature after Myka hiked up 6,000 feet?

• 35.6°F

• 38°F

• 34.6°F

• 30.4°F

Answer explanation

Myka's temperature drop is 5.4°F per 1,000 feet. After hiking 6,000 feet, the total drop is 5.4°F x 6 = 32.4°F. Starting from 68°F, the new temperature is 68°F - 32.4°F = 35.6°F, which is the correct answer.

Lana needs 24 1/4 yards of fabric to make a tablecloth. She has one piece of fabric that is 3 1/4 yards and another piece of fabric that is 4 1/8 yards. How many more yards of fabric does Lana need?

• 16 7/8 yards

• 17 yards

• 16 1/8 yards

• 17 1/8 yards

Answer explanation

Lana needs 24 1/4 yards. She has 3 1/4 + 4 1/8 = 7 3/8 yards. To find how much more she needs, subtract: 24 1/4 - 7 3/8 = 17 1/8 yards. Thus, she needs 17 1/8 yards more.

Myka plans to hike a total of 54 1/4 miles on her 5-day trip. She will hike 12 1/2 miles on each of the first three days and 10 3/8 miles on the fourth day. How many miles will Myka have left to hike on the fifth day?

• 6 7/8 miles

• 6 3/8 miles

• 10 miles

• 11 1/2 miles

Answer explanation

Myka hikes 12 1/2 miles for 3 days (37 1/2 miles) and 10 3/8 miles on the fourth day (10 3/8 miles). Total so far is 47 7/8 miles. Subtracting from 54 1/4 miles leaves 6 3/8 miles for the fifth day.

• $349.80

• $349.75

• $349.85

• $349.90

Owen's gaming system costs $199.95 and each controller costs $49.95. For 3 controllers, the total is 3 x $49.95 = $149.85. Adding these amounts: $199.95 + $149.85 = $349.80. Thus, the correct answer is $349.80.

• $2.66

• $2.67

• There are 10 blue jellybeans in the bag.

• There are 15 green jellybeans in the bag.

• There are 20 yellow jellybeans in the bag.

• There are 20 green jellybeans in the bag.

• There are 25 yellow jellybeans in the bag.

Answer explanation

There are 50 jellybeans total. Blue: 1/5 of 50 = 10. Green: 3/10 of 50 = 15. Remainder (yellow) = 50 - (10 + 15) = 25. Thus, the true statements are: 10 blue, 15 green, and 25 yellow jellybeans.
