a fundraiser raised $2400 , which was 3/5 of the goal . write an equation and solve it to find the goal
GuDViN [60]

First of all, 2400=0.6x is the equation

Now, we use cross multiplication

2400/1 = 3/5x

2400*5 = 3x

natka813 [3]

Answer:

7.5 Quarts

Step-by-step explanation:

D'Naisa mixed the following:

  • 1 gallon of orange paint
  • 2 quarts of yellow paint
  • 3 pints of red paint.

We are to determine in total, the number of quarts of paint that she mixed. this is done by converting each of the volume to quart.

<u>1 gallon of orange paint</u>

  • 1 gallon = 4 Quarts
  • Orange Paint=4 Quarts

<u>3 pints of red paint.</u>

  • 1 pint =0.5 quart
  • 3 Pints =3 X 0.5 Quart
  • =1.5 Quart of red paint

Therefore,

Total Volume of Paint Mixed in quart= Volume of Orange+Yellow+Red

=4+2+1.5

=7.5 Quarts
