Answer:
H2O and CO2 are examples of compounds
as the have different elements combined in them, and they don't show properties of combining elements..
So we know that the decimal place will move one right. Well basically let's assume she could have bought these expressions:
x 10 x 3.50 = 35.00
x 9 x 3.50 = 31.50 + 3.75 = 35.25
x 8 x 3.5 = 28 + 3.75 x 2 = 35.5
x 7 x 3.5 = 24.5 + 3.75 x 35.75
We know that there is a pattern. See how the cents goes .25 up each time. So we know she'd buy 6 reams of white because (6 x 3.5 = 21) + (4 x 3.75 = 15) = 36.
Adam has a greater rate of change, as seen by the larger slope. This means Adam is traveling faster than Katia.
You have to do 3x12 to get the answer which is 36.
