Question

Lester's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 80 espressos in all, 80% of which were single-shot. How many single-shot espressos did the cafe sell?

Answer 1

64

Explanation:

80% of 80 were single-shots

80/100 × 80

64

Answer 2

64 single-shot espressos

Explanation:

Let's say that the cafe sold x single-shot espressos. The total number of espressos sold was 80, and 80% of that total 80 were single-shot. So, we have the equation:

x = 80% * 80

Remember that % just means "out of 100". So, 80% = 80/100:

x = (80/100) * 80 = 6400/100 = 64 single-shot espressos

Hope this helps!
