some students want to order shirts with their school logo.onr company charges $9.00 per shirt plus a setup fee for $43.another c

Amanda [17]

Let's let x be the number of t-shirts.

So the first company charges $43 plus $9 per shirt. For x shirts, the cost is the base fee plus 9 times x, or $C=9x+43$ .

The second company charges a $58 fee plus $8 per shift. The cost is $C=8x+58$ .

Now, we want to find which fee is less when we are buying 20 shirts. We plug in 20 for x.

The first company charges $C=9(20)+43=223$ .

The second company charges $C=8(20)+58=218$ .

The costs are VERY close, but the second company ultimately charges less.

PLEASE HELP! I feel horrible and I'm crying so hard right now. This is due.

Lady bird [3.3K]

Answer:

Step-by-step explanation:

surface area of a rectangular prism = 2lw + 2lh + 2wh

Where l = length, w = width and h = height

The box has the following dimensions

length = 5 in

width = 3 in

height 2 in

Using these dimensions, we plug in the values into the formula

$SA=2(5*3)+2(5*2)+2(3*2)\\5*3=15\\15*2=30\\5*2=10\\10*2=20\\3*2=6\\6*2=12\\SA=30+20+12\\30+20+12=62$

Hence, the surface area = 62
