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
False -1 is not a solution.
Answer:
Number 1 I think sorry if I am incorrect.
It was $930.
To over check, multiply it by 20% , you will get $186.
Hope this helps !
earnings * 20 percent = 17
earnings * .2 = 17
divide by .2 on each side
earnings = 17/.2
earnings = $85.00
