Answer 1

Answer:

To determine the sales price of the sweaters the shirts and the pants, we need these equations: $2x+5y+3z=172$, $5x+8z=269$ and $4y+z=74$

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:

$2x+5y+3z=172$

The cost of the 5 sweaters and 8 pairs of pants is 269.

$5x+8z=269$

The cost of 4 shirts and 1 pair of pants is 74

$4y+z=74$

To determine the sales price of the sweaters the shirts and the pants, we need these equations: $2x+5y+3z=172$, $5x+8z=269$ and $4y+z=74$

Answer 2

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.
