Simone saved $15.45 from her allowance, had $7.37 in her piggy bank, and had $22.55 left from her birthday. How much money does Simone have?
Which mental math strategies will help her find the total? Select all that apply.
A.
Add $0.45 and $0.55 to make a dollar. Then, $7 + $22 + $1 = $30. Next, $30 + $15 = $45. Finally, add $0.37 to get $45.37.
B.
Drop all of the cents for each dollar amount. Then, $15 + $7 + $22 = $44.
C.
Round each dollar amount to the nearest dollar. Then, $7 + $23 = $30. Finally, $30 + $15 = $45.
D.
Add $0.05 to $15.45 to make $15.50. Subtract $0.05 from $22.55 to make $22.50. Then, $15.50 + $22.50 = $38. Finally, $38 + $7.37 = $45.37.
