The cost depends upon the number of long distance minutes, m, Amy uses. Write the rule that describes Amy's monthly cost.
1 answer:
Minutes(m) Cost
0 20
10 22
20 24
50 30
slope formula:
m = (y1 - y2) / (x1 - x2)
m = (20 - 22) / (0 - 10) = -2/-10 = 1/5 or 0.20
y = (1/5)(x) + 20
The rule that describes Amy's monthly cost is:
m = 1/5x + 20 or m = 0.20x + 20
Where x is the number of minutes spent on the call.

B + g = 16.....b = 16 - g
45b + 55g = 830
45(16 - g) + 55g = 830
720 - 45g + 55g = 830
-45g + 55g = 830 - 720
10g = 110
g = 110/10
g = 11 <=== there are 11 green cassettes
b + g = 16
b + 11 = 16
b = 16 - 11
b = 5 <=== there are 5 blue cassettes
