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

Total cost including sales tax = 230 + 16.1 = $ 246.1
Thus the total price with sales tax is $ 246.1

Answer:</h3>
<em>The theoretical probability to draw a black marble is </em><u><em>0.23</em></u><em>. </em>
Step-by-step explanation:
First add up the total amount of marbles in the bag.
14 gray marbles + 7 black marbles + 10 white marbles = 31 total marbles.
Since we need the odds of a black marble being drawn, divide 7 (the amount of black marbles) by 31 (the amount of total marbles).
7/31 ---> 0.22580645161 <u><em>(it is easiest to use a calculator on this step)</em></u><em> </em>
Lastly, round the decimal to the nearest hundredth.
0.22580645161 ---> <em>0.23</em>
<em>0.23</em> would be the odds of drawing a black marble.
