The expression c+0.07c or 1.07c can be used to calculate the price including tax.
Step-by-step explanation:
Given,
Cost of jacket = c
Sales tax = 7%
Amount of sales tax = 7% of cost of jacket
Amount of sales tax = [tex]\frac{7}{100}*c[/tex]
Amount of sales tax = 0.07c
Cost of jacket including tax = Cost of jacket + Amount of sales tax
Cost of jacket including tax = c + 0.07c = 1.07c
The expression c+0.07c or 1.07c can be used to calculate the price including tax.
