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:
The result of K's inaction causes an increase in the outstanding loan by $50
Explanation:
<em>Step 1: Determine the interest amount</em>
The interest amount can be determined as follows;
I=PRT
where;
I=interest amount
P=principal amount
R=annual interest rate
T=time
In our case;
I=unknown
P=$1,000
R=5%=5/100=0.05
T=1 year
replacing;
I=1,000×0.05×1=$50
<em>Step 2: Determine the total loan amount</em>
This can be expressed as;
A=P+I
where;
A=total loan amount
P=principal amount
I=interest amount
In our case;
A=unknown
P=$1,000
I=$50
replacing;
A=1,000+50=1,050
The loan amount due after a year=$1,050
The result of K's inaction causes an increase in the outstanding loan by $50
