Answer 2

Calculating the Remaining Coffee

To calculate the remaining coffee, we can follow these steps:

1. Calculate the Total Amount of Coffee: - The total amount of coffee is 18 portions multiplied by 20g per portion, which equals 360g.

2. Calculate the Amount Sold in the First Hour: - Half of the total amount of coffee was sold in the first hour, which is 360g / 2 = 180g.

3. Calculate the Amount Sold in the Second Hour: - An additional one-third of the total amount of coffee was sold in the second hour, which is 360g / 3 = 120g.

4. Calculate the Remaining Coffee: - To find the remaining coffee, subtract the amount sold in the first and second hours from the total amount of coffee: - Remaining coffee = Total amount - Amount sold in the first hour - Amount sold in the second hour - Remaining coffee = 360g - 180g - 120g - Remaining coffee = 60g

Therefore, 60g of coffee is left after the two hours.
