Answer: $90
Explanation: This problem can be solved by using following equation :-
Let John's hourly wage rate be J, Mary's hourly wage rate be M and Dennis hourly wage rate be D, therefore :-
Mary's rate will be :-
M = 2J............equation 1
AND,
J + D = $60 ..... equation 2
Similarly,
D = 1/3J
Now,putting the value of D in equation 2 we get,
J + 1/3J = $60
J = $45
Putting the values of J in equation equation 1 we get,
M = 2 * $45
= $90
So, Mary's hourly wage rate is $90

Answer:
$20,441.67
Explanation:
the present value of your house is $200,000, its future value = $200,000 x (1 + 5%)¹⁰ = $325,778.93
you can earn a 10% annual interest rate for 10 years, that means that we can use a future value of an annuity factor = 15.937
your annual investment = future value of the house / annuity factor = $325,778.93 / 15.937 = $20,441.67
