lina bought 3 apples. each apple cost 10¢. how much did the
apples cost altogether?

Explanation:

Step1: Estimate the height of a table

A table's height is usually around a few feet. 3 inches and 3 centimeters are too short. So, the best estimate is 3 feet.

Step2: Estimate the length of a pencil

A pencil's length is typically around a few inches. 4 feet is too long and 4 centimeters is too short. So, the best estimate is 4 inches.

Step3: Estimate the length of a real truck

A real - truck's length is usually in feet. 15 inches and 15 centimeters are too short. So, the best estimate is 15 feet.

Step4: Calculate the cost of apples

If each apple costs 10¢ and Lina bought 3 apples, we use multiplication. The total cost \(C = 10\times3\) cents.

Answer:

• The height of a table: 3 feet
• The length of a pencil: 4 inches
• The length of a real truck: 15 feet
• Cost of apples: \(10\times3 = 30\) cents. So the apples cost 30¢ altogether.
