y = 28 when x = 16

Solve. Dante's mom made 2 liters of cocoa. Dante and his 7 friends each drank a serving of cocoa. If each serving is 235 milliliters, how much cocoa is left?

Answers

Answer:

120 millimeters or 0.12 liters

Step-by-step explanation:

To solve this question :

we have to convert liters to millimetersmultiply the serving of coca by the number of people that consumed the cocasubtract the answer gotten from the step above from 2 litters

1 liter = 1000 millimeter

2 liters = 2 x 1000 = 2000mm

8 people drank cocoa = 8 x 235 = 1880mm

Amount of cocoa left over = 2000 - 1880 = 120mm or 0.12 liters
