1. The problem asks to match each expression to its meaning among Total Cost, Amount of Tax, and Tax Rate. 2. The expressions given are: - $0.07$ - $0.07p$ - $1.07p$ 3. Important rules: - Tax Rate is the percentage rate applied, usually a decimal like $0.07$ for 7%. - Amount of Tax is the tax rate multiplied by the price $p$, so $0.07p$. - Total Cost is the original price plus tax, which is $p + 0.07p = 1.07p$. 4. Matching each expression: - $0.07$ is the Tax Rate. - $0.07p$ is the Amount of Tax. - $1.07p$ is the Total Cost. 5. Therefore, the matches are: - $0.07$: Tax Rate (C) - $0.07p$: Amount of Tax (E) - $1.07p$: Total Cost (G) 6. Final answer: C,E,G
