The system of equations that models the given situation is:
x+y =531
y=2x
She bought 177 long sleeved shirts and 354 short-sleeved shirts.
Step-by-step explanation:
Given
x = Long-sleeves shirt
y= short sleeves shirts
Then
Nancy bought 531 shirts for her business.
x+y =531 Eqn 1
She bought 2 times as many short-sleeve shirts as long-sleeve shirts.
y=2x Eqn 2
Putting y=2x in eqn 1
[tex]x+y=531\\x+2x = 531\\3x=531\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3}=\frac{531}{3}\\x=177\\Putting\ x=177\ in\ eqn\ 2\\y=2(177)\\y=354[/tex]
She bought 177 long sleeved shirts and 354 short-sleeved shirts.
