The cafe served 72 regular coffees.

Coffee Served - Count

Here are the steps to find the number of regular coffees served:

Calculate the total number of regular coffees as a percentage of the 80 coffees served in total: 80 x 90% = 72

The answer is 72 regular coffees.

The method used for this problem is simple arithmetic calculation, specifically percent calculation.

Percent calculation is used to find the proportion of a number in terms of a percent. To perform a percent calculation, you multiply the original number by the percent (expressed as a decimal) and then round the result to the desired number of decimal places. In this case, the original number is 80 and the percent is 90, which we first convert to 0.90 (by dividing by 100).

You could determine that this method was used because the problem statement asked for the proportion of regular coffee in terms of percent (90%) of the total number of coffees served (80). To find this proportion, you needed to multiply 80 by 0.9, which is equivalent to 80 * 90%.
