Question

Susan purchased the following items at Target: 4 notebooks at $1.29 each, 2 pens at $2.15 each, and 1 package of markers for $3.19. If the sales tax is 6%, what is the total amount Susan had to pay?

Answer 1

Susan must pay `$13.41`

Explanation:

Total cost of:
notebooks: `4times1.29=5.16`
pens: `2times2.15=4.30`
markers: `1times3.19=3.19`

Amount of money without tax: `5.16+4.30+3.19=12.65`

If tax is `6%`, then it is tax is basically `6/100` of `12.65`
ie `6/100times12.65=0.759`

Therefore, Susan must pay `0.759+12.65=13.41`
