Four friends each purchased a hat for $12.50
mrs_skeptik [129]

Answer:

$70 each

Step-by-step explanation:

If 4 friends each buy a hat, that would be $50 because that is $12.50X4=%50.00. Then, Since the total is $190 and $50 is off the chart, you would be left with $140 to spend on two t-shirts. Finally, since they are the same price, you divide $140/2=$70. Each t-shirt is $70.

Let me know if you need clarification and I will help the best I can. Have a nice day. :)
