Jill and Erika made 4 gallons of lemonade for their lemonade stand. How many quarts did they make if then charge $2:00 per quart
notka56 [123]

Answer:

Number of quarts=16

Money earned=$32

Step-by-step explanation:

Given

  • 4 Gallons of lemonade is prepared
  • They charge $2 for a quart

1 Gallon= 4 Quarts

Therefore Number of quarts

= \text{number of gallons} \times 4\\= 4 \times 4\\=16

Therefore Number of quarts of lemonade prepared by them = 16 quarts

As they charge $2 for each quart

⇒

Total money made if they sell it all

=\text{number of quarts} \times 2\\= 16 \times 2\\=32

Therefore, if they are to sell all the lemonade that they prepared

They would earn=$32

Vladimir says that the equation of the line that passes through points (negative 5, negative 3) and (10, 9) is y = four-fifths x
love history [14]

Answer:

Vladimir and Robyn both are correct.

Step-by-step explanation:

Let us check whether the points (-5,-3) and (10,9) are on the line y = \frac{4}{5}x + 1 or not.

The equation of the straight line passing through the given points (-5,-3) ans (10,9) is \frac{y - 9}{9 + 3} = \frac{x - 10}{10 + 5}

⇒ 5(y - 9) = 4(x - 10)

⇒ 5y = 4x + 5

⇒  y = \frac{4}{5}x + 1 .............. (1)

So, Vladimir is correct.

Now, Robyn says that the line passes through the points (-10,-7) and (-15,-11).

Then, both of the points satisfy the equation (1).

Therefore, Vladimir and Robyn both are correct. (Answer)
