He got 4 percent right. 16 percent of 15 is 4 :)
Answer:
the amount borrowed is ≅ $527
Step-by-step explanation:
Given that;
simple interest rate r = 180% p.a
Let the amount borrowed (principal) be $x.
time t = 4 weeks = 28 days
= 28/365 year
= 0.0767 year
we all know that :


Simple interest = 0.13806x
Total amount to be paid after 4 weeks= Interest+Principal
= x + 0.13806x
= 1.13806x
Thus;
1.13806x = $600
x = $600/ 1.13806
x = $527.21
Hence; the amount borrowed is ≅ $527
X would be 196. All you have to do is divide 5/7 one each side of the equation and you would get x = 196. I hope this helped and make sure to make this the brainliest answer :)
The answer is z=20 because 25-6 is 19 and rounded that is 20
2/3 x -4 = -2 add 4 to both sides
2/3 x -4 +4 = -2 +4
2/3 x = 2
mutliply both sides by 3/2
(3/2) * (2/3) x = (3/2) * 2
x =3
