Bowling centers in the United States made $2,800,000,000 in 1990. their receipts in 1998 were $2,764,000,000. What was the average change in revenue for each of these 8 years? What? What does it mean by reciepts? Someone please explain!

OpenStudy (amistre64):

receipts are just a record of how much they made

OpenStudy (anonymous):

okay but i still do not get it. how do i solve the problem?

OpenStudy (amistre64):

difference in cash -------------- difference in years

OpenStudy (amistre64):

without any more information; thats all you can do with it

OpenStudy (amistre64):

28... - 27.... ------------ 8

OpenStudy (amistre64):

236,000/8 if i see it right

OpenStudy (amistre64):

forgot a few zeros lol

OpenStudy (anonymous):

so 36,000,000/8? 4,500,000?

OpenStudy (amistre64):

2,800,000,000 2,764,0 ---------- 36,000 ... yeah

OpenStudy (anonymous):

so its 4,500,000 or is it 36,000? thats what you put.....

OpenStudy (anonymous):

oh wait so it is 4,500,000

OpenStudy (amistre64):

36,000,000 is the difference; divide that over 8 years and you get the 4,500,000

OpenStudy (anonymous):

so the average change is.....

OpenStudy (amistre64):

$4 500 000 per year
