Question

Irma's Cafe has regular coffee and decaffeinated coffee. This morning, the cafe served 80 coffees in all, 48 of which were regular. What percentage of the coffees were regular?

Answer 1

To find the percentage of regular coffees served at Irma's Cafe, we can use the following formula:

\[
\text{Percentage of regular coffee} = \left( \frac{\text{Number of regular coffees}}{\text{Total number of coffees}} \right) \times 100
\]

From the information provided:
- Number of regular coffees = 48
- Total number of coffees = 80

Now, we can substitute the values into the formula:

\[
\text{Percentage of regular coffee} = \left( \frac{48}{80} \right) \times 100
\]

Now, calculating the fraction:

\[
\frac{48}{80} = 0.6
\]

Next, convert to percentage:

\[
0.6 \times 100 = 60
\]

Thus, the percentage of the coffees that were regular is:

\[
\boxed{60\%}
\]
