If 50 people go up the mountain and 40 people come down the mountain in a group then 7 people come down but then they go back up the mountain but then 8 people leave in a second group, what happened to the 2 people left ?

a) they died
b) they came down last
c) they fell off a cliff
d) they got lost

If you want to make your teacher laugh I say D but if you want to get it right I say B

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

if you was gonna solve for a, a is a   < -12
