A box contains erasers of two different colors: green and blue.
The ratio of green to blue is 7:5. If
there are 48 total erasers in the
box, how many total green erasers
are there?

There will be 28 green erasers. I know that the ratio is also 28:20, so there are 20 blu erasers.

Step-by-step explanation:

I time 7 by 4 and 5 by 4 to get the new ratio. I counted the ratios to get to 48.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
