At a clearance sale, the price of a TV was discounted 40%. The discount price was $375. What was the original price?

615
525
625
635
645

Correct Answer

A. 625

Explanation

The original price of the TV can be calculated by dividing the discount price by (100% - discount percentage) and then multiplying by 100. In this case, the discount percentage is 40%, so (100% - 40%) = 60%. Dividing the discount price of $375 by 60% gives us $625, which is the original price of the TV.

Ms. Hanson invests $500 in the stock market. After ten years, if her investment is worth 300% of its original cost, how much will it then be worth?

1000
5000
1500
5500

Correct Answer

A. 1500

Explanation

After ten years, Ms. Hanson's investment will be worth 300% of its original cost, which means it will be worth 3 times its original value. If her original investment was $500, then 3 times that amount is $1500. Therefore, her investment will be worth $1500 after ten years.

At a factory, a baseball is put in a box that has a volume of 512 cubic inches. Each boxed baseball is then put in a larger box for shipment. The shipping box holds 24 boxed baseballs in each layer and contains a total of 96 boxed baseballs. What is the volume of the shipping box?

12,288 cubic inches
49,152 cubic inches
61,440 cubic inches

Correct Answer

A. 49,152 cubic inches

Explanation

The volume of the shipping box can be calculated by multiplying the volume of each boxed baseball by the number of boxed baseballs in the shipping box. Since each boxed baseball has a volume of 512 cubic inches and there are 96 boxed baseballs in the shipping box, the volume of the shipping box is 512 cubic inches multiplied by 96, which equals 49,152 cubic inches.

The area of a rectangle is 36 square centimeters; its perimeter is 30 centimeters. What are the dimensions of the rectangle?

2 cm by 18 cm
3 cm by 12 cm
4 cm by 9 cm
6 cm by 6 cm

Correct Answer

A. 3 cm by 12 cm

Explanation

The area of a rectangle is calculated by multiplying its length and width. In this case, we are given that the area is 36 square centimeters. To find the dimensions, we need to determine two numbers that multiply to give 36. The only pair that satisfies this condition is 3 and 12, as 3 multiplied by 12 equals 36. Additionally, the perimeter of a rectangle is calculated by adding twice the length and twice the width. In this case, we are given that the perimeter is 30 centimeters. By substituting the dimensions into the perimeter formula, we can verify that the dimensions 3 cm by 12 cm indeed result in a perimeter of 30 centimeters.
