Violet finds some nickels and pennies under the couch cushions. How much money (in dollars) does she have if she has 140 nickels and 70 pennies? How much money (in dollars) does she have if she has xx nickels and yy pennies? Total value, 140 nickels and 70 pennies (dollars):

Total value, xx nickels and yy pennies (dollars):

$7.70

Step-by-step explanation:

140x5=700

70= well 70

700+70=770

770/100+7.7

7.7 in money is 7 dollars and 70 cents

:)

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 !
