For this you will need to calculate the number of sweaters - 7x. Then you need to calculate the number of shirts - 9y. Last you need to calculate the number of pants - 12z. To balance the equation, you must calculate the total price $172+$269+$74 = $515. The equation is 7x+9y+12z = $515.
Answer:
To determine the sales price of the sweaters the shirts and the pants, we need these equations: [tex]2x+5y+3z=172[/tex], [tex]5x+8z=269[/tex] and [tex]4y+z=74[/tex]
Step-by-step explanation:
Consider the provided information.
It is given that x represents sweaters, y represents shirts and z represents pants.
The cost of the 2 sweaters , 5 shirts and 3 pairs of pants is 172.
Therefore, the required system of equation is:
[tex]2x+5y+3z=172[/tex]
The cost of the 5 sweaters and 8 pairs of pants is 269.
[tex]5x+8z=269[/tex]
The cost of 4 shirts and 1 pair of pants is 74
[tex]4y+z=74[/tex]
To determine the sales price of the sweaters the shirts and the pants, we need these equations: [tex]2x+5y+3z=172[/tex], [tex]5x+8z=269[/tex] and [tex]4y+z=74[/tex]
