Answer 1

Answer: Number of lightbulbs that he used = 21 lightbulbs

1 dozen of light bulbs = 12 light bulbs

Jaoquin buys 3 dozens

3 dozens of lightbulbs = 3 * 12 lightbulbs

3 dozens of lightbulbs = 36 lightbulbs

This means that :

The number of light bulbs Jaoquin bought = 36

The number of lightbulbs that remain = 15

The number of lightbulbs that he used = (Number of lightbulbs that he buys) - (Number of lightbulbs that remains)

Number of lightbulbs that he used = 36 - 15

Number of lightbulbs that he used = 21 lightbulbs
