Question

circle b is 10% bigger than circle a. circle c is 10% bigger than circle b. what % is c bigger than a?

Answer 1

20%

Step-by-step explanation:

from circle a, you add 10% for circle b. You do the same from circle b to circle c. If you add 10% each time, and you do this twice, you must add them together. 10+10 is 20
