Write an expression for the amount she added:
Dimes: 2(0.10)
Quarters: 3(0.25)
Nickels: 6(0.05)
Now write an expression for what she took out:
Quarters: 2(0.25)
Dimes: 5(0.10)
Now combine them:
2(0.10) + 3(0.25) + 6(0.05) - 2(0.25) - 5(0.10)
Simplify:
0.20 + 0.75 + 0.30 - 0.50 - 0.50
1.25 - 1.00 = 0.25 increase.
