Answer:

Cost before sales tax= 16 dollars

Total cost= 17.16 dollars

Step-by-step explanation:

We know the sales tax rate is 7.25 percent.

To find the cost from the tax rate, we divide the cost of the sales tax by the rate.

1.16/0.0725 = 16 dollars

Now to find the total cost, add the cost before the tax rate by the sales tax amount.

16+1.16= 17.16 dollars

Answer: OPTION B.

Step-by-step explanation:

Given the following System of equations:

$\left \{ {{3x-5y=19} \atop {x+y=1}} \right.$

You can use the Elimination Method to solve it. The steps are:

1. You can mutliply the second equation by -3.

2. Then you must add the equations.

3. Solve for the variable "y".

Then:

$\left \{ {{3x-5y=19} \atop {-3x-3y=-3}} \right.\\.....................\\-8y=16\\\\y=\frac{16}{-8}\\\\y=-2$

4. Now that you know the value of the variable "y", you must substitute it into any original equation.

5. The final step is to solve for "x" in order to find its value.

Then:

$x+(-2)=1\\\\x=1+2\\\\x=3$

Therefore, the solution is:

$(3,-2)$
