Answer:
Mila had $48 initially
Step-by-step explanation:
Let the amount of money they had be x
Mila spent $42; what is left would be x-42
Samuel spent $36: what is left would be x-36
So, what Mila had left is half of what Samuel has; that would be;
x-42 = 1/2(x-36)
2(x-42) = x -36
2x-84 = x -36
2x - x = 84 -36
x = $48
Undistribute z
divide both sides by (v-k^5)
(560+48x)/x. After owning the washing machine for x years, with operating cost of $48 each year, the total amount of operating cost is 48x. We should also add the one-time cost of buying the washing machine, which is $560. The total cost is 560+48x. Since x years have past, the average annual cost is (560+48x)/x, or 48+560/x dollars.
The third choice does not represent a proportional relationship because the y-intercept ≠ 0.
Hope that helped you.
