(A) 6

(E) 21

10% more than A = (1 + .10) = 1.10A

If percent MORE is > 100, the method is the same: add the percentage in decimal form to 1

250 percent MORE than original =(1 + 2.5)=(3.5)
(original + 250% of original)
(original)*(1 + 2.50) = (original)*(3.5)

A grows 6 inches
B grows 250% more than A = 3.5A
(3.5) * 6 = 21 inches

OR
100% MORE than 6 = 12 (=twice)

200% MORE than 6 = 18 (=thrice)
50% MORE than 6 = 3 (=\(\frac{1}{2}\) of 6 more)

(250%) = (200%+50%) = (18+3) = 21

Answer E

*Percent OF means multiply:
10% of 100 = (.10) * 100 = 10
200% of 5 = (2) * 5 = 10

Percent MORE THAN and percent GREATER THAN
indicate addition after multiplication. Both mean:
add the given percent to the original number

You could find 250% of A=6 and add to original number
250% of 6?\(\frac{250}{100}=(\frac{5}{2}*6)=15\)
Add 15 to original: \((15 + 6) = 21\)

OR combine multiplication and addition
250% more than A=(100% of A+250% of A)= 350% of A
250% more than A = (1A + 2.5A) = 3.5A
(3.5) * 6 = 21
