2.1 liters of coffee were equally distributed to 30 cups how many millimeters of coffee were in each cup
sattari [20]

Answer: 70 ml of coffee in each cup


Step-by-step explanation:

1 liter = 1000 ml

<em>∵ Amount of coffee in each cup </em>= <u>70 milliliters</u>

Melvin Marshall bought 20 Mothers Day Muffins for Mama-Melanie, Auntie-Marlene, Grandma-Melissa, Cousin Carmela and Sister-Shami
amid [387]

Answer:

The number of  Carmel muffins is 8 and the number of lemon muffins is 12.  

Step-by-step explanation:

Melvin Marshall bought a total of 20 Muffins . Some were camel-glazed muffins and some were lemon. The Carmel muffins cost $3 each while the lemons cost $2.5 . The number of carmel muffins and lemon muffins can be calculated as follows

total number of muffin =  20

Let

a  = number of carmel - glazed muffins

b = number of lemon muffins

a + b = 20.............(i)

The total cost

3a + 2.50b = 54................(ii)

Combine the equations

a + b = 20.............(i)

3a + 2.50b = 54................(ii)

a = 20 - b

insert the value of a in equation (ii)

3(20 - b) + 2.50b = 54

60 - 3b + 2.50b = 54

60 - 54 = 0.5b

0.5b = 6

divide both sides by 0.5

b = 6/0.5

b = 12

Insert the value of b in equation (i)

a + b = 20.............(i)

a + 12 = 20

a = 20 - 12

a = 8

The number of  Carmel muffins is 8 and the number of lemon muffins is 12.
