Question

a coffee shop served 24 people before 7:00 a.m. 2/3 had regular coffee 1/8 had decaf and the remaining order specialty coffee how many customers ordered a specialty coffee

Answer 1

Since 2/3 of 24 had regular coffe, then:

`24\cdot(2)/(3)=(24\cdot2)/(3)=(48)/(3)=16`

We have that 16 people had regular coffe. Now for the people that had decaf:

`24\cdot(1)/(8)=(24)/(8)=3`

There were 3 people that drank decaf. The remaining had the specialty coffe, then:

`24-16-3=24-19=5`

Therefore, 5 people asked for the specialty coffee
