Let the price of one T-Shirt be "x".
Therefore, the price of two T-Shirts will be 2x....Equation 1
Now, it is given that the cost of shoes is $22......Equation 2
Michael and Morgan together pay a total of $12 (from the gift certificate) plus $36.50=$48.50.........................Equation 3
Therefore, the above equations give us:
[tex]2x+22=48.50[/tex]
[tex]2x=48.50-22=26.50[/tex]
[tex]\therefore x=13.25[/tex]
Thus, the cost of one T shirt is $13.25
