Astore bought a bike for $145. they marked up the cost by 150%. what is the new selling price?

150% = 1.50

145 x 1.50 = 217.50

 the selling price is $217.50

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
