Answer: the remaining credit after 79 minutes of call is $15.52
Step-by-step explanation:
let x represent the number of minutes of call.
Let y represent the remaining credit after x minutes of call.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (17.2 - 19.84)/(65 - 43)
m = - 2.64/22 = - 0.12
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 65, y = 17.2 and m = - 0.12 into y = mx + c. It becomes
17.2 = - 0.12 × 65 + c
17.2 = - 7.8 + c
c = 17.2 + 7.8
c = 25
The linear function becomes
y = - 0.12x + 25
Therefore, the remaining credit after 79 minutes of call is
y = - 0.12 × 79 + 25
y = - 9.4 + 25
y = 15.52
Answer:
235.980931
Step-by-step explanation:
To solve this problem you must find 86% of 19,396.
To do this, let's start by turning 86% a decimal to multiply.
86% will become 0.86
Now, we multiply 0.86 by 19,396.
We get the answer, 16680.56
The question says about, so we need to round it.
When rounded we get 16681.
That means 16681 bulldogs were registered in 2003.
Hope this helped you! :)
