Question

Eddie's Tea Shop has caffeinated tea and decaffeinated tea. During the lunchtime rush, the tea shop served 32 teas in all, 25% of which were caffeinated. How many caffeinated teas did the tea shop serve?

Answer 1

Answer: 8 teas were caffeinated

Explanation:

To solve is to turn 25% into a decimal:

This is 25/100 turned into 0.25

*Multiply this by 32

This gives the number 8

*To do this, multiply without the decimal: 25 x 32 = 800

Then place the decimal back 2 places to the left of the last number:

8.00
