Irene knows there are 2 cups in 1 pint. She writes the equation c=2p to find the number of cups, c, in any number of pints, p. U
Natasha2012 [34]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as there are no options to select from.

However, a general explanation is as follows.

Given

2\ cups = 1\ pint

Required

Is c = 2p a correct expression?

Let

c = cups

p = pint

So:

2\ cups = 1\ pint

becomes

2 * c = 1 * p

2c = p

Divide both sides by 2

c =\frac{1}{2}p

Hence:

c = 2p is incorrect

harina [27]
Call the price of the bike before mark up 'x', then we have:

x + 0.25x = 210
      1.25x = 210 
             x = 168

Therefore, the bike cost $168 before 25% price increase.
