Jillian has $2000 in credit card debt. Every month, she pays $200 to the credit card company at the beginning of the month, the credit card company applies a 2% monthly interest rate to the balance at the end of the month, and her balance is always rounded to the nearest cent. After the end of five months, what is her ending balance after interest?

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
