A T-shirt design company charges your team an initial fee of $25 to create the team's design. Each T-shirt printed with your des
Korvikt [17]

Answer:

Part A)

C(t)=25+8t

Part B)

C(35)=\$305

Step-by-step explanation:

We will let <em>t</em> represent the total number of t-shirts printed.

We are charged an initial fee of $25. So, for our linear model, our constant is 25. And each t-shirt printed costs an additional $8. So, for <em>t</em> t-shirts, it will cost an additional 8<em>t</em> dollars.

Part A)

So, from the above information, we can write the following function:

C(t)=25+8t

Where <em>C(t)</em> is the total cost for <em>t</em> shirts.

The 25 represents our initial fee and the <em>8t</em> represents the cost for <em>t</em> t-shirts.

Part B)

So, if we have a team of 35 members, we will need 35 t-shirts.

Then the total cost will be given by:

\begin{aligned}C(35)&=25+8(35)\\&=25+280\\&=\$305\end{aligned}

So, it will cost a total of $305.

Find the area of the figure. (Sides meet at right angles.)
Lubov Fominskaja [6]

Answer:

the area is 68 feet

Step-by-step explanation:

-first pretend that one spot is filled and if you do that the whole rectangle is 8 by 10.

- the area of something is length times width and so 8 times 10 is 80

- however, we can't pretend that we don't have a hole anymore so to figure out that tiny rectangles area we have to find its width and length which is 4 and 3.

- 4 times 3 is 12 and since we have that we subtract 12 from 80 and we get 68.
