The drama club is selling short-sleeved shirts for $5 Let x represent the number of short-sleeved shirts
each, and long-sleeved shirts for $10 each. They hope to ordered and let y represent the number of long-sleeve
sell all of the shirts they ordered, to earn a total of
shirts ordered.
$1,750. After the first week of the fundraiser, they sold How many short-sleeved shirts were ordered?
3
of the short-sleeved shirts and 15 of the long-sleeved
How many long-sleeved shirts were ordered?
shirts, for a total of 100 shirts.
This system of equations models the situation.
5x + 10y = 1,750
**+ y = 100

This data is Inaccurate Data
Equations of the system are When The situation is described is modeled by the following system of equations: Step first 5x + 10y = 1,750 Step second x + y = 100Where are
x = number of short-sleeved shirts y = number of long-sleeved shirtsDivide first by 5:
Then third step will be x + 2y = 350Multiplye secondly by -2:
-2x - 2y = -200
Add with the third one -x = 150 x = -150 Then, The value of x should not be negative. also, This happens because the problem is inaccurately stated. Not even selling 100 of the $10 shirts we can get to $1,750. If the total shirts sold was 200, then it secondly x + y = 200 And then x = 50, y=150 was an acceptable solution.Learn more:

Innacurate Data
Step-by-step explanation:
System of Equations
The situation described is modeled by the following system of equations:
5x + 10y = 1,750 [1]
x + y = 100 [2]
Where
x = number of short-sleeved shirts
y = number of long-sleeved shirts
Divide [1] by 5:
x + 2y = 350 [3]
Multiply [2] by -2:
-2x - 2y = -200
Add with [3]:
-x = 150
x = -150
The value of x should not be negative. This happens because the problem is inaccurately stated. Not even selling 100 of the $10 shirts we can get to $1,750.
If the total shirts sold was 200, then
x + y = 200 [2]
And x = 50, y=150 was an acceptable solution
