2. A property agent sells a house for $320000 of which he receives a commission of 1.5%. Calculate the amount of commission he receives.

For 2) use : C = V * P/100. Where C= commission, V = value of property and P = commission rate (1.5)
For 3) $9/12 = $? cost for each...sells them at $1.20 each, then find the percentage of the profit.

1) You need to multiply the three numbers, 7,3 and 2, but what ever it takes to get the number 3 to become 350.

In the future post only one problem per post AND show your work. This is a not a website where you drop off your homework and pick it up later. You the student must solve your own problem with helpful hints from the helpers on this forum. Please post back with your work with the 1st problem.
