The solar energy company where you work as a sales representative is running a 20% off sale on its residential solar panels. if a homeowner pays $20,000.00 for the panels at a discounted price, what was the original cost of the panels?

24,000

Step-by-step explanation:

20,000 x .20 = 4,000

20,000 + 4,000 = 24,000

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
