    Denise buys a soda for 90 cents, a candy bar for $1.20 and a bag of chips for $2.90. Assuming a 3.5 percent sales tax, how much change would she receive from a $10 bill

    1. Change = $10 - Total Bill

    Total Bill = (Soda + Candy Bar + Bag of Chips) * 1.035
    Total Bill = ($0.90 + $1.20 + $2.90) * 1.035
    Total Bill = $5 * 1.035
    2. Total Bill = $5.18

    Plug Equation (2) into Equation (1), we have:
    Change = $10 - $5.18
    Change = $4.82
