Answer 1

Given Data:

The cost of one box of 216 tissues is $1.29.

The cost of one calculator is $ 7.99.

The cost of five 3-subject notebooks is $ 0.69 each.

The cost of one 10-pack blue pens is $ 0.99.

The cost of one dozen No.2 pencils is $ 1.09.

The cost of one 5-pack of colored pens is $ 2.49.

The cost of two 150-sheet packs of loose-leaf paper is $ 0.99 each.

The cost of one 3-ring binder is $1.99.

The cost of one glue stick is $0.44.

The sales tax is 5%.

The total cost excluding sales tax can be determined as,

$\begin{gathered} c=(1.29)+(7.99)+(3\times0.69)+(0.99)+(1.09)+(2.49)+(2\times0.99)+(1.99)+(0.44) \\ =21.71. \end{gathered}$

The sales tax can be determined as,

$\begin{gathered} ST=c\times\frac{5}{100} \\ =21.71\times\frac{5}{100} \\ =1.0855 \end{gathered}$

Thus, the sales tax is 1.0855.

The total bill can be determined as,

$\begin{gathered} A=c+ST \\ =21.71+1.0855 \\ =22.7955 \end{gathered}$

Thus, the total bill including sales tax is $ 22.7955.
