Solution

According to the bar graph, the minimum amount of caffeine in a 5-ounce cup of percolated coffee is approximately 40 milligrams. Therefore, the minimum
amount of caffeine in two 10-ounce cups of percolated coffee, which is the same as the minimum amount of caffeine in four 5-ounce cups, is approximately
(40)(4), or 160 milligrams. The minimum amount of caffeine in a 12-ounce caffeinated soft drink is approximately 30 milligrams. So, the minimum amount
of caffeine in two 10-ounce mugs of percolated coffee and one 12-ounce caffeinated soft drink is approximately 160+30, or 190 milligrams. The correct
answer is Choice B.

As always, my mistake is that I read a question not carefully! I don’t know how to accustom myself to read the task carefully the first time?

Slow down.

You waste some second more but the probability you pick it correct is higher
