The total price with sales tax is $ 246.1
Cost of cellphone = $ 210
Cost of battery charger = $ 15
Cost of batteries = $ 5
So total cost can be calculated by adding cost of cellphone and Cost of battery charger and Cost of batteries
Total cost = 210 + 15 + 5 = $ 230
Given that sales tax is 7%
sales tax = 7% of total cost
sales tax = 7 % of 230
[tex]\text {sales tax }=\frac{7}{100} \times 230=16.1[/tex]
Total cost including sales tax = 230 + 16.1 = $ 246.1
Thus the total price with sales tax is $ 246.1
