Sagot :
x-54= 66 x being the amount of caffeine in the cup of coffee.
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:
[tex]66=x-54[/tex]
Solving for x
[tex]x=66+54[/tex]
x = 120
Therefore, there is 120 milligrams of caffeine in a cup of coffee.
