F it rose 10% that means that it is now worth 110% of what it was a year ago. So set up an equation: 297 = 110% of x297 = 1.1 x270 = x So it was worth $270 a year ago.
To answer this question, you need to know how many drops go into atheism test tube.
Each drop is 1/8 milliliter. The test tube is 30 milliliter.
So, divide 30 by 1/8 to see how many times 1/8 goes into 30.
30 divided by 1/8 = 30 times 8 = 240
It takes 240 drops (that's a lot!) to fill up the test tube.
Hope this helps!
