Can someone me i really appreciate in advanced

E1. 
a) So it says you need an equation for the amount spent and the amount collected. She spends money when she "used $6 worth of yarn for each scarf" and when she "paid $50 to rent a table." 
The expression for the yarn is 60x (x representing the yarn per scarf). 
And the expression for how much she spent with the table is simply 50, since it's a one-time thing. 
So how much she spent in total is 60x + 50.

She collected money when "she sold every scarf for $10". 
The expression would be 10x.

The system of equations would be: 
y = 60x + 50 
y = 10x

Definitely
