Marissa has twice as much money as Frank. Christina has $20 more than Marissa. If Christina has $100, how much money does Marissa have?

Marissa has $80

Step-by-step explanation:

are you sure its asking for Marissas money or Franks money? but its fine if its Marissa too

Christina: 100

Marissa: 20 less than her

So 100-20=80

And Marissa has $80

Just in case, heres how to find Franks money:

100-20=2x

subtract 20 from both sides

80=2x

divide by 2

40=x

And Frank has $40

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

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.
