Total Attendence = Mean Attendence × No. of Incidents
= 24,500 × 25
= 612,500.
Answer:

Step-by-step explanation:
Let
x ----> the number of minutes
y ----> the amount of fuel in gallons
we know that
The linear equation in slope intercept form is equal to

where
m is the unit rate or slope
b is the y-intercept or initial value
we have that
The unit rate or slope is equal to

----> initial value (value of y when the value of x is equal to zero)
substitute

The number of orders in is equal to the number of orders out in month 4 (April). It appears the solution represents the time at which warehouse shipments caught up with order quantities.
_____
For this table to make any sense, we have to assume that the year started with 3 orders in January, and that one order was shipped in January. Then the number of orders was 1 or 2 each month after that, and the number of orders shipped per month was 2 each month after that. That is, the tables represent year-to-date totals of orders in and out.
<em>Alternate Interpretation</em>
If the numbers here are actual orders in and out in each of the listed months, it appears the warehouse is getting better at shipping orders. That is, they are increasing the shipment rate by 2 orders a month each month. They will eventually ship enough to cover the total number of orders in (total of 20 by April), but total shipments through April only amount to 16 orders.
His mistake is that he used the differences of 6, 10 and 14 instead of the differences of 7, 17 and 31.
i.e. for a linear function, the y values should have a constant rate of change and not the differences.
2x - 3 > 11 - 5x |add 3 to both sides
2x > 14 - 5x |add 5x to both sides
7x > 14 |divide both sides by 7
x > 2
x = 4
