Answer:
$57

Step-by-step explanation:
Given that:
Earnings per hour for washing cars = $9
Earnings per hour for walking dogs = $6
Number of hours for which car washing is done = 
Number of hours taken for walking dogs = 
Earnings for
hours for washing cars = Per hour earnings multiplied by number of hours = $9
Earnings for
hours for walking dogs = Per hour earnings multiplied by number of hours = $6
Total earnings by both = $(
)
Now, given that
Number of hours spent washing cars = 5 hours
Number of hours spent walking dogs = 2 hours
Therefore, total earnings by both = 9
5 + 6
2 = <em>$57</em>
The answer is c to your question
Answer:
Option (D)
Step-by-step explanation:
At every 6 crew workers number of clean up kits required = 1
Therefore, for 1 crew worker number of kits required = 
And number of kits required for w workers =
= w ÷ 6
If w = 54
Number of kits required = 
If w = 60
Number of kits required = 
If w = 66
Number of kits required = 
Therefore, table given in Option (D) is the correct table.
No it isn't.
Explanation:
x/y * y = (y-6) * y
x = y^2 - 6y
A function gives just one y for every x
In this case there will always be 2 y's for every x
Example:
y can be
y = 6
or
y =−6
(0,-6) & (0,6)
