Answer:

2*12*40 + 20*40*3 + 3240 + 500

Step-by-step explanation:

Each worker is paid per hour, so lets figure out how much each is paid with 40 hours.

First are 2 workers paid 12 per hour. 12 per hour for 40 hours is 12*40, and since there are 2 multiply that by 2, so 2*12*40

Then there are 3 paid 20 per hour so that is 20*40*3

Materials are 3240 and on top of that she wants a 500 dollar profit, which means after getting all that money she wants 500 more. So just add all these numbers up.
