Lauren in making 15 liters of mimosas for a brunch banquet. Orange juice costs her $1.50 per liter and champagne costs her $12 p
PSYCHO15rus [73]

Answer:

  • 10 liters of orange juice
  • 5 liters of champagne

Step-by-step explanation:

Let c represent the number of liters of champagne Lauren uses. Then (15-c) will be the number of liters of orange juice. The total cost of the mix will be ...

  12c +1.50(15-c) = 5.00(15)

  10.5c = 52.50 . . . . . subtract 22.50, simplify

  52.50/10.5 = c = 5 . . . . divide by the coefficient of c

Then the amount of orange juice is ...

  15 -c = 15 -5 = 10 . . . . liters

Lauren should use 5 liters of champagne and 10 liters of orange juice.

OLEGan [10]
1584 yards cubed.

Convert all the measurements to inches.
9*12=108
11*12=132
Multiply 108 and 132 to get the area.
108*132=14256
Multiply 14256 by 4 to get the volume.
14256*4=57024
Divide by 36, because there are 36 inches in a yard.
57024/36= 1584 Yards Cubed
