Answer:

15% of the teas are caffeinated

Step-by-step explanation:

Use the formula:

part/whole = t/100%

where t will be representing the percent of caffeinated tea.

Plug in the given to the formula shown above:

9/60 = t/100

Solve using cross product

(9 x 100) = (60 x t)

900/60 = 60t/60

15 = t
