Kristen is considering having two different companies create t-shirts for her Math Club. Here are the two company chooses:
Awesome T-shirts charges a $80 up-front fee and $2.50 for each t-shirt, t.
Walden's Tee Company charges a $50 up-front fee and $4.00 for each t-shirt, t.
Kristen needs to order 100 t-shirts. Which company should she choose and why?
Answer:
Awesome T -shirts
Step-by-step explanation:
They cost less by a margin of $120,meanign better deal
9514 1404 393
Answer:
Awesome T-shirts; the order is for more than 20 shirts
Step-by-step explanation:
The cost of "t" t-shirts at Awesome will be ...
A = 80 +2.50t
The cost of "t" t-shirts at Walden's will be ...
W = 50 +4.00t
These costs are equal when ...
A = W
80 +2.50t = 50 +4.00t
30 = 1.50t . . . . . . . . . . . . subtract 50+2.50t
20 = t . . . . . . . . . . . . divide by 1.50
If the order is for more than 20 t-shirts, the lower per-shirt price at Awesome will mean the total cost is lower at Awesome. Kristen is planning to order 100 t-shirts, so will get a lower price at Awesome.

Answer:
3x
Step-by-step explanation:
the distance between 0 and C = x
to make b 3 times distance of c to 0 we should multiply by 3
so X × 3 = 3X
if the distance of c to 0 equal to 1 cm means that x = 1
3x = 3
so be should place b 3 cm away from 0

How should the decimal point in 0.937 change to get the correct answer to 0.937 ÷ 10²?
A. move it 2 place to the right
B . move it 2 places to the left
C .move it 3 places to the right
D .move it 3 places to the left
Answer:
B.
Step-by-step explanation:
When moving a decimal point 2 places to the right you are multiplying. When moving it to the left you are dividing. In this case we are moving 2 places to the left which the exponent 2 is representing. If you were to move 3 places to the right or left you would need to have a three as your exponent.

Answer:
[tex]\huge\boxed{\sf{36y-63}}[/tex]
Step-by-step explanation:
Hello.
Use the Distributive Property and simplify.
Remember that it states: a(b+c)=ab+ac
Where a, b, and c can be either constants or variables.
Now, simplify the given expression:
