Andrea' s record label released her new albu. Andrea wants to know when she has sales of at least $20,000 per week. She uses the relate equation below determine when sales will be at least this amount, where t represents time in weeks.

$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.
