Joannie lent $200 to her sister. four years later, her sister repaid her in full with $228. what simple annual interest rate did joannie's sister pay? a. 3.0% b. 3.5% c. 4.0% d. 4.5%

Ok, so lets convert all the percents into decimals to help us solve this problem

A 3.0%= 0.03

B 3.5%= 0.035

C 4.0%= 0.04

D 4.5%= 0.045

Now, we can multiply $200 by all the decimals we just converted to see which one will add up to $208

200*0.03= 6200+6=206 (this is not equal to 208 so it's not A)

200*0.035=7200+7= 207 (Still does not equal 208, so it's not B)

200*0.04= 8200+8=208 C is your answer

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

may i see the picture? it would a lot, xox
