Which could be the first step in solving the equation represented by the model below?
Add 4 positive unit tiles to each side.
Remove 4 unit tiles from each side.
0 Add 6 positive unit tiles to each side.
0 Remove 6 unit tiles from each side.

step-by-step explanation:

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

+

    $3.00

$68.00

so sunghee has $68.00
