Last week Fred had eleven dollars. He washed cars over the weekend and now has fifty-three dollars. How much money did he make washing cars?

• $42

• $44

• $40

• $45

Answer explanation

Fred had $11 and now has $53. To find out how much he made washing cars, subtract his initial amount from his current amount: $53 - $11 = $42. Therefore, he made $42 washing cars.

Mary found 98 seashells and 34 starfishes on the beach. She gave Nancy some of her seashells. She has 39 seashells left. How many seashells did she give to Nancy?

• 59

• 60

• 61

• 62

Answer explanation

Mary initially had 98 seashells and now has 39 left. To find out how many she gave to Nancy, subtract 39 from 98: 98 - 39 = 59. Therefore, Mary gave Nancy 59 seashells.

The store has CDs and DVDs that you need. How many packs of DVDs can you buy with one hundred eighty dollars if one pack costs twelve dollars?

• 15

• 14

• 13

• 16

Answer explanation

To find out how many packs of DVDs you can buy with $180, divide 180 by the cost of one pack, which is $12. So, 180 ÷ 12 = 15. Therefore, you can buy 15 packs of DVDs.

Elena and her best friend found some money in an envelope. They split the money evenly, each getting $25. How much money did they find?

• $50

• $45

• $55

• $60

Answer explanation

Elena and her friend split the money evenly, each receiving $25. Therefore, the total amount of money they found is 25 + 25 = $50. Thus, the correct answer is $50.
