Answer 5

Right. In 40 years I'll be 99.4 years old. Can hardly wait.
Now use the same method to find "40% more than 2 teaspoons of butter."

Answer 6

so c?

Answer 7

I'd prefer you share how you found that.

Answer 8

well, 0.4 = 40%, if im right, and 0.4 * 2 = the answer im supposed to get. am i correct?

Answer 9

But wouldn't 0.4 * 2 give you LESS butter, not more butter?

Answer 10

"40% more" actually requires multiplying 2 tsp by 1.40 (not by .40).

Answer 11

Try it. What is 1.40 of my age (71)?

Answer 12

69.6?
