Answer:
Its the second option. 742.5
Helen subtracted 17 from the right side of the equation when she should have added 17. Adding 17 to both sides would have gotten x/y by itself.
The answer is 'Helen should have added 17 to both sides of the equation'.
3x + 6 + x + 2 = 180
4x = 180 - 8
4x = 172
x = 43
A = 3x + 6 = 3×43 + 6 = 129 + 6 = 135
Answer:
Step-by-step explanation:
We know that:
FV = $130,000
r = 4% (semiannually )
We need to find number of periods (n) , the child is now 6 years old, until the child is 18 is 12 years. But it is the rate is compounded semiannually, so n = 12*2 = 24
We have the fomula to find out periodic payment (see the attached photo)
=> pmt = 3326.288
