To find the cost for 1 marker u have to divide 20 by 6. 20/6 is around $0.3. So 30c for one marker
Answer:
the first term is 67
Step-by-step explanation:
A finite arithmetic sequence has 12 terms. The last term Is 100 and the common difference is 3.
the formula for nth term is
Equation for 12th term is
a_12 is the last term, a1 is the first term and d is the common difference
a12= 100, d= 3
Subtract 33 from both sides
a_1= 67
So the first term is 67
Loan is the 12,000 at 8% annual
292.96 each month for 4yrs
292.96*48months=14,062.08-12,000=2062.08
Answer:
The remaining credit after 45 minutes of calls is $18.70
Step-by-step explanation:
Here, we have a linear model to work with
Let us have the coordinates as follows;
(time calling time, credit remaining)
So we have two points as follows;
(24,21.64) and (35,20.10)
The slope will be;
(20.1-21.64)/(35-24) = -1.54/11 = -0.14
So the equation looks like;
y = -0.14x + c
To get the y-intercept, we simply substitute a point
Let us use (35,20.10)
20.10 = -0.14(35) + c
c = 20.10 + 4.9
c = 25
So the full equation is;
y = -0.14x + 25
So for 45 minutes, simply substitute 45 for x
We have this as:
y = -0.14(45) + 25
y = -6.3 + 25 = $18.70
