Well I would answer it this way. Hope it helps-you have four friends plus yourself. That makes 5. You will then take the $400 x 5(how many people) + the cost of tools $525. 2000 + 525=$2525
profit of each=$400
total profit=4*400= $1600
cost=$525
total income=1600+525=$2125
total profit=4*400= $1600
cost=$525
total income=1600+525=$2125
