Hi!
To answer this, first we have to find how much 1 notebook costs. We can do this by dividing:
Cost/amount = ?
Or in this case
5.25/5 = 1.5
Now we have to find how much 3 notebooks cost. We can do this by multiplying:
Cost of one x amount = ?
Or in this case
1.5 x 3 = 3.15
The answer is 3.15
Hope this helps! :)

In
order to solve for a nth term in an arithmetic sequence, we use the formula
written as:<span>
an = a1 + (n-1)d
where an is the nth term, a1 is the first value in the sequence, n is the term
position and d is the common difference.
First, we need to calculate for d from the given values above.
d=11-8=3
at n=100
</span>an = a1 + (n-1)d
<span>a100 = 11 + (100-1)3
a100 = 308</span>
Answer:
You found the area of each side of the rectangular prism, subtracting the missing area from the front and back sides of the prism. Then you added together the area of all 6 faces to find the total outer surface area.
