Answer:

72 parts

Steps:

Convert the 4 hours into minutes. There are 60 minutes in an hour. Therefore, 4 hours = 240 minutes.

Divide 240 minutes by 40 minutes. This equals 6. Therefore, the machinist can produce the 12 parts 6 times in 4 hours.

Finally, multiply the 12 parts by the 6 times he can produce. Therefore, the machinist can produce 72 parts in 4 hours.

A store pays $ 56 for a cell phone. The store marks the price at 20%. What is the quantity of the mark?
galben [10]

Answer:

The quantity of the mark is $11.20

Step-by-step explanation:

Given that:

Amount paid by store for cell phone = $56

Hence,

The quantity of the mark is $11.20
