Answer: to maximize profit the management must continue charging $40 per room because it will obtain a profit of $1,920 better than $1,870 if it rises the rate.
Step-by-step explanation:
<u>Profit without the increase</u>
60 (number of rooms) * $40 (rate per room) = $ 2,400
costs of day to service = 60 (rooms) * $8 (costs day to service)= $480
Total Profit = $2,400 - $480 = $1,920
<u>Profit with the increase</u>
55 (5 fewer than before) * 42 (rate with the increase) = $ 2,310
costs of day service 55 (rooms) * 8 ( costs day to service) = $440
Total Profit = $2,310 -$440 = $1,870
Answer:
13,0
Step-by-step explanation:
12=3(x-9)
divide both sides by three
4=x-9
add 9 to both sides
x=13
so, the x intercept is (13,0)
Answer:
7
4
Step-by-step explanation:
The <u>actual values</u> are shown on the given graph as <u>blue points</u>.
The <u>line of regression</u> is shown on the given graph as the <u>red line</u>.
From inspection of the graph, in the year 2000 the actual rainfall was 43 cm, shown by point (2000, 43). It appears that the regression line is at y = 50 when x is the year 2000.
⇒ Difference = 50 - 43 = 7 cm
<u>In 2000, the actual rainfall was </u><u>7</u><u> centimeters below what the model predicts</u>.
From inspection of the graph, in the year 2003 the actual rainfall was 44 cm, shown by point (2003, 40). It appears that the regression line is at y = 40 when x is the year 2003.
⇒ Difference = 44 - 40 = 4 cm
<u>In 2003, the actual rainfall was </u><u>4</u><u> centimeters above what the model predicts.</u>
