Use the two graphs to help complete the statements below
2 answers:
A) Rate: 5 lawns per day
B) Slope: 5 lawns per day
Step-by-step explanation:
A)
For this graph, we want to find the following ration:
where
- change in lawns moved is the change in the variable along the y-axis, since the lawns moved is represented on the y-axis
- change in time is the change in the variable along the x-axis, since time is represented along the x-axis
By taking the last point in the graph (6,30) and the point (0,0), to have the most accurate measurement, we have:
t = 6 days
lawns moved = 30
Therefore, the rate is
lawns per day
B)
Here in graph B, similarly we want to find the slope of the curve, which is given by
where
is the change in the y-variable
is the change in the x-variable
Taking the last point in the graph (6,30) and the point (0,0), in order to get the most accurate measurement, we have:
Therefore the slope is
lawns per day

Answer:
Option C
Step-by-step explanation:
You forgot to attach the expression that models the cost of the camping trip during the three days. However, by analyzing the units, the answer can be reached.
The total cost has to be in units of $.
There are two types of costs in the problem:
Those that depend on the number of days ($/day )
Those that depend on the number of students and the number of days ($/(student * day))
If there are 3 days of camping and b students, then you have to multiply the costs that depend on the days by the number of days (3), and the costs that depend on the number of students you have to multiply them by 'b'
So, if the costs that must be multiplied by 'b' are only those that depend on the number of students, the coefficient of b must be:
3 days (Cost of training + Cost of food Miscellaneous expenses :).
Therefore the correct answer is option C:
C. It is the total cost of 3 days per student of Mr. Brown, with training, food and miscellaneous expenses.
The expression that represents the total expense should have a formula similar to this:
y = 3 ($ 100b + $ 200) + $ 1050
