A cell phone cost $210 a battery charger costs $15 and batteries cost $5 .what is the sales tax and total price for purchasing t
Savatey [412]

The total price with sales tax is $ 246.1

<h3><u>Solution:</u></h3>

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

\text {sales tax }=\frac{7}{100} \times 230=16.1

Total cost including sales tax = 230 + 16.1 = $ 246.1

Thus the total price with sales tax is $ 246.1
