Answer:
The pizza heats up an average of 7.50 degrees per minute
Step-by-step explanation:
The table shown
Time (minutes) Temperature (degrees Celsius)
1 2.52
7 47.547
13 92.592
Since the pizza was heated at a constant rate, we can model the experiment as a line, where the slope represents how fast the pizza was heated
Slope
m = (y2 - y1)/(x2 - x1)
Let
(x1,y1) = (7, 47.547)
(x2,y2) = (13, 92.592)
m = (92.592 - 47.547)/(13-7)
m = 7.5075
The pizza heats up an average of 7.50 degrees per minute
Given:
Cost of printing a catalog: flat rate of $52 and $0.20 per copy.
C = 52 + 0.20x
C is the total cost of printing x number of copies.
x = 500
C = 52 + 0.20(500) = 52 + 100 = 152
x = 1000
C = 52 + 0.20(1000) = 52 + 200 = 252
x = 1500
C = 52 + 0.20(1500) = 52 + 300 = 352
x = 2000
C = 52 + 0.20(2000) = 52 + 400 = 452
x = 2500
C = 52 + 0.20(2500) = 52 + 500 = 552
