g = girls in class
b= boys in class
g = 2b-1
girls + boys =26
g+b=26
substitute g = 2b-1
2b-1 +b =26
combine like terms
3b-1 =26
add 1 to each side
3b -1+1 = 26+1
3b = 27
divide each side by 3
3b/3 = 27/3
b = 9
There are 9 boys

The amount of punch leftover would be equal to 31 serving with 170ml remaining.
One liter is a metric unit to measure the amount of quantity or volume.
One liter is equal to one thousand milliliters.
Jennifer made 5 L of punch for her party. Her brother made another 750 ml.
we know that 1 liter = 1000 milliliters
5 liters would be
5 × 1000 = 5000ml
When we combine the two batches, we get
5000 + 750 = 5750
Thus, punching leftover
5750 ÷ 180 = 31.94
31 serving with 170ml remaining
Therefore, The amount of punch leftover would be equal to 31 serving with 170ml remaining.
