Answer:
Non-proportional; the rate of change is $40/hour
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u>and the line passes through the origin</u>
Let
x -----> the number of hours
y ----> The total charge in dollars
The equation of the line in slope intercept form is equal to
where
m is the slope
b is the y-intercept
we have
substitute
This relationship is not proportional, because the line not passes through the origin
therefore
Non-proportional; the rate of change is $40/hour

You just have to find the greatest common factor for both 28 and 24, which is 4. You can make 4 packets with 7 milk chocolates and 6 dark chocolates.
15y - 9 < 36
15y < 36 + 9
15y < 45
y < 45 ÷ 15
y < 3
