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

$x+y=531\\x+2x = 531\\3x=531\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3}=\frac{531}{3}\\x=177\\Putting\ x=177\ in\ eqn\ 2\\y=2(177)\\y=354$

She bought 177 long sleeved shirts and 354 short-sleeved shirts.

IgorC [24]

Answer:

Yes! Our total savings on gas proportional to the number of beverages you purchase.

Step-by-step explanation:

Here, each liter of gas costs $3.

Every beverage you purchase you save $0.20.

So, if you purchase for $9, you will save 3*$0.20 = $0.60

So, this is proportional because when increase in purchase, there is proportional increase in savings.
