Answer:
B
Step-by-step explanation:
You can just move upper y equation and it will be:
6x+3(3x-5)=15
6x+9x-15=15
15x-15=15
15x=30
x=2
Lois will sell her tee-shirt for $13.20
The percentage profit = 
× 100
Profit = Selling price - cost price
Cost price is the total amount expended in making the tee-shirts
cost price includes cost of buying blank shirt , cost of fabric paint and amount Lois pay herself
cost of buying blank shirt = $1
cost of fabric paint = $1
amount Lois pay herself = 
x $6
x $6 = $9
Total cost price = $1 + $1 + $9 = $11
0.2 = 
profit = 11 x 0.2 = $2.2
$2.20 = selling price - $11
selling price = $11 + 2.20 = $13.20

Answer:
The player with the most runs had a rush of 1,240 yards
Step-by-step explanation:
In this question, we are asked to calculate the number of yards that was rushed by one of two person given their combined run and an extra information.
Firstly, let the person that had the smaller number of rush have a rush of x rushes. The second person has a rush of 4 times the other. This makes a number of 4x rushes
By adding both together, we have a total of 1550 yards
Mathematically, this means that x + 4x = 1550
5x = 1550
x = 1550/5 = 310 rushes
The second player had a rush of 4x and that is 4 * 310 = 1,240 rushes
