Answer:

There is 120 milligrams of caffeine in a cup of coffee.

Step-by-step explanation:

A cup of brewed tea has 54 milligrams less caffeine than a cup of brewed coffee. A cup of tea has 66 milligrams of caffeine.

Let the amount of caffeine in a cup of coffee be = x

In the equation form, we can denote this as:

$66=x-54$

Solving for x

$x=66+54$

x = 120

Therefore, there is 120 milligrams of caffeine in a cup of coffee.
