1. the local theater charges $8 for a child’s ticket and $12 for an adult’s ticket.
a.) write an expression that describes the amount of money needed to buy x child tickets and y adult tickets for a group.
b.) evaluate the expression to find the total price of 9 tickets for children and 4 tickets
for adults.

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 !
