Answer:
$9.61 per shirt
Step-by-step explanation:
You take the total cost of $48.05 and divide it by the number of t-shirts which is 5.
48.05/5 = 9.61
25% is equal to 100/25=1/4
We can substitute this into an equation to get the total number of wells where n can be equal to the total number of wells.
1/4*n=50
n/4=50
n=50*4
n=200
The total number of wells that were drilled was 200.
If x=16-4y then in your other equation 3x+4y=8 you can put that where x is to get:
3(16-4y)+4y=8
Then multiply brackets to get:
48-12y+4y=8
Simplify:
48-8y=8
Rearrange:
40=8y
Divide through by 8:
y=5
Then put y=5 back into x=16-4y to get x:
x=16-4(5)
x=16-20
x=-4
C I think pretty sure tho
