Agatha christie's company held a local 2-day training program for her and 3 co-workers. they were all paid their regular wages for the time they were released from their regular work. these wages totaled $850 for the group. refreshments and lunch were served for a cost of $45 per person. the instructor who conducted the training charged $300 per day. supplies for the program were $17 per person. travel expenses for the group totaled $105. what was the total cost for the seminar?

$1803

Step-by-step explanation:

850 + 45(4) + 300(2) + 17(4) + 105 = 1803

many reason,

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
