An employee working at an electronics store earned $3582 for working 3 months during the summer. what did the employee earn for the first two months?

$2388

Step-by-step explanation:

He earned $3582 for 3 months.

He earned 1/3 of $3582 for each month.

For 2 months, he earned 2/3 of $3582.

Now we calculate 2/3 of $3582.

2/3 * $3582 =

= 2/3 * $3582/1

= (2 * $3582)/(3 * 1)

= $7164/3

= $2388

reduce the friction between its moving parts
