In 2011 grace paid $12.95 for a box of cards and $0.44 each stamp for 16 stamps. What was the total cost in dollars and cents of the box and stamp

Cost for each:

box of cards=$12.95

stamp=0.44

The number of quantity for each:

box of cards=1

stamp=16

Now the equation should be as follow:

quantity(box of cards)+quantity(stamp)

1($12.95)+16($0.44)

$12.95+$7.04

$19.99

The total cost is $19.99 or simply 19 dollars and 99 cents

Step-by-step explanation:

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
