Skyler buys 8 t-shirts and 5 hats for $220. the next day, he buys 5 t-shirts and 1 hat for $112. what is the cost of each t-shirt and each hat?

shirt =20

hat =12

Step-by-step explanation:

cost of shirts * number of shirts + cost of hats * number of hats = total cost

Let the cost of shirts = s and the cost of hats =h

s * 8 +  h * 5 = 220

s * 5 + h * 1 = 112

We will use elimination to solve this system of equations.  Multiply the second equation by -5.

-5(s * 5 + h * 1) =-5( 112)

-25s -5h = -560

Now we need to add it to the first equation

 8s + 5h = 220

-25s - 5h = -560

-17s          = -340

Divide each side by -17

-17s/-17 = -340/-17

s = 20

The cost of a shirt is $20

Now we need to find the cost of a hat.

5s+h = 112

Substitute s=20 into the above equation.

5(20)+h = 112

100+h = 112

Subtract 100 from each side.

100-100+h = 112-100

h= 12

The cost of a hat is 12

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
