Question

Derrick went to the grocery store and purchased of a pound of ham for $6.99 per pound, of a pound of cheese for $3.99 per pound, a loaf of bread for $2.49, and 1 gallon of milk for $2.89. The sales tax on food items in his state is 4.3%. What is Derrick's total for the groceries after tax? Round your answer to the nearest cent.

Answer 1

$\begin{gathered} \frac{3}{4}\text{ pounds of ham = \ 6.99 per pound} \\ \frac{1}{4}\text{ pounds of ch}eese=\text{ \ 3.99 per pound} \\ a\text{ loaf of bread=\ 2.49} \\ 1\text{ gallon of milk= \ 2.89} \end{gathered}$

The total purchase is

$\begin{gathered} 1\text{ pounds of ham= \ 6.99} \\ \frac{3}{4}\text{ pounds =}\frac{3}{4}\times6.99=\frac{20.97}{4}=\text{ \ }5.2425 \\ \\ 1\text{ pound of che}ese=\text{ \ 3.99} \\ \frac{1}{4}\text{ pound of che}ese=\frac{1}{4}\times3.99=\text{ \ }0.9975 \\ \\ \text{total}=0.9975+5.2425+2.49+2.89=\text{ \ }11.62 \end{gathered}$

After paying tax his total will be

$\begin{gathered} \frac{4.3}{100}\times11.62=\frac{49.966}{100}=\text{ \ }0.49966 \\ \\ \text{total}=0.49966+11.62=\text{ \ }12.11966 \\ \text{total}=\text{ \ }12.12 \end{gathered}$
