Juan's Cafe has regular coffee and decaffeinated coffee. This morning, the cafe served 70 coffees in all, 70% of which were regular. How many regular coffees did the cafe serve?

Answer :

The cafe served 49 regular coffees.

How to calculate this

You can use the proportion of regular coffees to the total number of coffees to find out how many regular coffees were served.

If 70% of the coffees served were regular, that means that 100-70 = 30% of the coffees served were decaffeinated.

To find out how many regular coffees were served, you can use the following proportion:

(Number of regular coffees) / (Total number of coffees) = 70% / 100%

You can then cross-multiply and solve for the number of regular coffees:

Number of regular coffees = (70/100) * (Total number of coffees)

Given the Total number of coffees = 70, you can substitute that and get:

Number of regular coffees = (70/100) * 70 = 49

Therefore, the number of regular coffees which the cafe served was 49.
