Sunghee empties her piggy bank and finds that she has 200 quaters,150 dimes, and 300 pennies. how much money does she have? explain

So first find out how much each is worth.
Quarter= 25 cents
Dime= 10 cents
Pennies= 1 cent

Then multiply each by how much each is worth.

200                     150                  300
x                         x                    x   1
  25                       10              
                                 300
1000                    1500
+                          
4000                                      

5000                                  
  
Then count 2 from the back and add a period.

$50.00
$15.00
$3.00

And then add them

  $50.00
+
  $15.00
