Answer:
60%
Step-by-step explanation:
If I get you right, you're asking for the percentage gain to the nearest percentage, right?
Now to do this, we need to get the amount of profit she made. That's quite easy, we only need to subtract the cost price from the selling price. And that equals $15 - $9.38 that equals $5.62.
Now, we divide this value by the cost price and multiply by 100% to get the percentage gain.
I.e 5.62/9.38 × 100%.
That gives 59.9% , which equals 60% when approximated to the nearest percentage.
(40+41+41+45+48+48+49+49+49+40)/10 = 460/10 = 46
mean = 46
7m is all that you should be left with. Are you just trying to isolate your variable?
8 costumes. Not 8/0.75.
Write down 8 costumes, that's your answer.
Assuming that the remaining part of the picture is white, 2/3 of the picture is white.
The painting as a whole = 1. 1 - 1/3 (the amount that is black) = 2/3. Thus, 2/3 is white.
