Answer:
yes
Step-by-step explanation:
Remember, mean is average. So first you add them all up, and then divide by the total number. All the dollars added up and then divided by 6 equals 59. So, working backwards, if you multiply 6 (the number of categories) by 59 you get the total of all money earned from every category. 6 times 59 equals 354. But if you add what you can see right now, it only equals 274. So the t-shirt total must be the difference between the two... 80 dollars.
The first one is -763.1 and the second one is -24
(8/9-3/9)*2/3=5/9*2/3=10/27
