Answer:
Step-by-step explanation:
Let n represent the number of copies made.
Let y represent the cost of making n copies.
If we plot y on the vertical axis and n on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (66 - 48)/(197 - 50)
m = 18/147 = 0.122
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 = 66, y = 48 and m = 0.122 into y = mx + c. It becomes
48 = 0.122 × 66 + c = 8.052 + c
c = 48 - 8.052
c = 39.948
The linear function that describes the cost of a printing job would be
y = 0.122n + 39.948

The formula in getting the arithmetic sequence:
an = a1<span> + (n – 1)d.
</span>
We can substitute the values in order for us to know how many terms the sequence has.
an = 7373
a1 = 1313
d = 303
an = a1<span> + (n – 1)d
</span>7373 = 1313 + (n-1) 303
7373 = 1313 + 303n - 303
-303n = 1313 - 303 - 7373
303n = -1313 + 303 + 7373
303n = 6363
n = 21
So, there are 21 terms in the sequence given.
