Answer 1

Start by calculating the tax of the meal by multiplying by the 8%, which can be writen in decimal form as 0.08

`\begin{gathered} tax=45.67\cdot0.08 \\ tax\approx3.65 \end{gathered}`

Continue by calculating the tip.

first add the tax and the meal cost together

`\begin{gathered} 45.67+3.65 \\ 49.32 \end{gathered}`

Calculate the tip by multypling by 15% in its decimal form 0.15

`\begin{gathered} tip=49.32\cdot0.15 \\ tip\approx7.40 \end{gathered}`

Add together the cost of the meal, tax and tip to find the total cost

`\begin{gathered} totalCost=45.67+3.65+7.40 \\ totalCost=56.72 \end{gathered}`
