300 Find the difference (500-100=400) then halve the sum(200). Add the halved sum to the lowest number in the equaion(100) or subtract the halved sum(200)from the largest number in the equation(500) one:500-100=400 two:400/2=200 Three: 200+100=300 or 500-200=300

It is 200% of 150. 75% of 400 = 300 % rate =300/150 *100% = 200%
287 + 491 + 200 + 500 + 300 + 500 + 280 + 400 + 290 + 490 = 3738
