$44*5= $220 total spent
$20*60=$1200 total money a trader gets

Hope I didn't mess up for your sake.
First subtract the original high from the new high:
567 - 540 = 27 more vacuums sold.
Now divide the increase amount by the original high and multiply that by 100 to get the percentage:
27 / 540 = 0.05
0.05 * 100 = 5% Increase.
Answer:
0.019 or 1.9%
Step-by-step explanation:
The probability that a randomly selected roll used by the manufacturer contains flaws is determined by the probability of a flawed cotton roll occurring (1% x 70%) added to the probability of a flawed nylon roll occurring (4% x 30%) .

The probability that a randomly selected roll contains flaws is 0.019 or 1.9%
13/18
