Question

Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long. A customer

came in during the morning and bought 120 centimeters of the velvet Another customer
bought an additional 14 meters during the afternoon. How much crimson velvet does Malik's
shop have left? Write the answer in centimeters
​

Answer 1

The shop had 1680 cm left of velvet.

Explanation:

In order to solve this problem we need to convert all the measurements to the same length unit, since there are two measurements in meters and one in centimetres we will convert the last one to meter. To do that we need to divide by 100 as shown below:

`m_1 = 120 \text{ cm} = 1.2 \text{ m}`

To calculate the quantity of velvet left we need to subtract what was bought from the original amount, so we have:

`\text{velvet left} = 32 - 1.2 - 14\\\text{velvet left} = 16.8 \text{m}`

Since the problem wants the answer in cm, we need to multiply the found value by 100, we have:

`\text{velvet left} = 16.8*100 = 1680\text{ cm}`

The shop had 1680 cm left of velvet.
