Answer:

-3n + 18

Step-by-step explanation:

an = dn + (a - d)

The difference is -3.

The first term is 15.

an = -3n + (15- (-3))

an = -3n + 15 + 3

an = -3n + 18

Answer:

aₙ= 18 -3n

Step-by-step explanation:

15, 12, 9, 6

Given AP with first term= 15 and common difference= -3

aₙ=a₁+(n-1)d= 15+(n-1)*(-3)= 15 - 3n+3= 18-3n

aₙ= 18 -3n

Sarah the yearbook editor and Mrs Moore the yearbook sponser are reviewing costs to produce the yearbook. New yearbook design so
mario62 [17]

Answer:

I think the answer would be best supported with an equation. Then everything will fall into place

Step-by-step explanation:

We have a pre-set amount of $800. That will not change.

The key word here is each. It costs $15 to print <em>each</em> yearbook. Each depends on how many yearbooks are bought.

We will use y to represent the amount of yearbooks bought, and t to represent the total cost.

Equation:

800 + 15y = t

<u>Let's try an example:</u>

<em>The yearbook club finds that 50 people have decidedly bought yearbooks! They are so excited! But they have a problem. They don't know how much the whole thing is going to cost: the yearbook software cost AND the amount they must spend on printing each yearbook. What is the total cost?</em>

So we have an equation: 800 + 15y = t. Now we just substitute in the numbers and voila! We get our answer. Let's solve!

800 + 15y      = t

800 + 15(50) = t      (y is the amount of yearbooks bought. 50 people

800 + 750     = t       bought yearbooks).

1150               = t      (t is the total cost of everything).

Our total cost is $1150! That is how much it'll cost to make all the yearbooks, including the yearbook software.

I hope this helps!
