A)Plugging in our initial statement values of y = 16 when x = 10, we get:
16 = 10k
Divide each side by 10 to solve for k:
16/10=
k = 1.6
Solve the second part of the variation equation:
Because we have found our relationship constant k = 1.6, we form our new variation equation:
y = 1.6x
Since we were given that x, we have
y = 1.6()
y = 0
B)Plugging in our initial statement values of y = 1 when x = 15, we get:
1 = 15k
Divide each side by 15 to solve for k:
1/15
=15k
k = 0.066666666666667
Factor the numerator and denominator and cancel the common factors.
The answer would be 1/4
the correct answer would be C. $121.75
Hope I helped.
Assuming a simple interest model for this information, the interest due at maturity will be:
I=(PRT)/100
where:
P=principle
R=rate
T=time
thus
I=1500×120/364×10/100
I=$49.45
Answer: $49.45
