Answer:
The nike store offers the best deal
The saving per shirt is $2.50
Step-by-step explanation:
Here, we want to compare the prices offered in the two stores
In footlocker, you can get 3 shirts for $55.50
The sales per shirt is thus;
55.5/3 = $18.50
For Nike,
5 shirts for $79.99 which is almost $80
So the price per shirt is $80/5 = $16
We can see that the price at the nike store is better
The difference leading to the savings is;
18.5-16 = $2.50
So you save $2.50 buying from the nike store

Answer:
The required system of equations to the given parametric equations are:
5x1 - x2 = 6
x1 + x2 = -6
Step-by-step explanation:
Given the parametric equations:
x1 = t
x2 = -6 + 5t
Eliminating the parameter t, we obtain one of the equations of a system in two variables, x1 and x2 that has the solution set given by the parametric equations.
Doing that, we have:
5x1 - x2 = 6
Again a second equation can be a linear combination of x1 and x2
x1 + x2 = -6 + 6t
x1 + x2 = -6 (putting t=0)
And they are the required equations.
