The smaller wheel rolled
.. 4*2πr = 8πr . . . . feet
The larger wheel rolled
.. 4*2π*2r = 16πr . . feet
The larger wheel traveled (16πr -8πr) = 8πr feet farther than the small wheel.
Answer:
The new mortgage repayment is $10,580.69
Step-by-step explanation:
As at the time Douglas lost his job,he has already made repayments on the mortgage for a period of 7 years,by extending the repayment period by another 7 years,Douglas now have a period of repayment of 30 years now(30-7+7).
The new repayment yearly can be computed using the pmt formula in excel as given below:
=pmt(rate,nper,-pv,fv)
rate is the interest rate on mortgage given as 4.25%
nper is the period of repayment now 30 years
pv is the current of balance of $177,533.62
fv is the total amount repayable on the mortgage and it is not known hence taken as zero
=pmt(4.25%,30,-177533.62,0)=$10,580.69
Answer:

x=8
5*8-2y=30
40-2y=30 . subtract 40 from both sides
-2y=-10 . divide both sides by-2
y=5
