Let x be the cost of 1 shirt and y be the cost of 1 scarf.
Since, 3 shirts and 2 scarves cost $94, we have,
3x + 2y = 94
Since the number of unknowns is greater than the number of equations (2 > 1), the above system has infinitely many solutions.
If t is the cost of 1 scarf, then
3x + 2t = 94
3x = 94 - 2t
x = 
For different values for t, we will get different values for x.
Set t = 2.
Then, x = 
= 
= 
= 30
So, if the cost of 1 scarf is $2, then the cost of 1 shirt is $30.

Answer:
0.636
Step-by-step explanation:
First off, we'll interpret the fraction bar to mean "divided by." This means that 7/11 is the same as 7 divided by 11.
Second, you have requested to see 2 decimal places in your answer, so we'll write the 7 as 7.00 instead (a 7 with 2 zeros after the decimal point).
Now, we'll just do what the fraction bar says: divide 7.00 by 11:
And that's about it! 7/11 written as a decimal to 3 decimal places is 0.636.
