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?

9514 1404 393

  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: the answer is simply nothing.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
