Answer:
880 minutes
Step-by-step explanation:
cost = 0.05(per minute) + basic fee
y = 0.05x + 15
59 = 0.05x + 15
subtract 15
44 = 0.05x
divide by 0.05
x = 880
Slope = (0 - 4)/(-5-5) = -4/-10 = 2/5
y = mx + b
4 = (2/5) (5) + b
4 = 2 +b
b = 2
equation
y = 2/5x + 2
4 ÷ 2 = 2
2 ÷ 4 = 1/2
As we can see, the order in which the numbers are divided yielded different results.
