The easiest way to solve this is to take the amount of each coin and multiply it by its value. Afterwards add each total together to determine the amount of money that Ann has.
145 pennies X $0.01 = $1.45
42 dimes X $0.10 = $4.20
12 quarters X $0.25 = $3.00
$1.45 + $4.20 + $3.00 = $8.65
Therefore Ann has $8.65
