Final answer:
The woman should send $82.39 to the state government for the sales tax collected, calculated by subtracting the starting cash from the ending cash and multiplying the result by the sales tax rate of 7%.
Step-by-step explanation:
To calculate the amount of sales tax the woman should send to the state government, we first determine the total sales amount without the starting cash. The woman starts with $230, and at the end of the day, the register has $1,407. The total sales amount is $1,407 - $230 = $1,177.
Since the sales tax rate is 7%, we convert this percentage to a decimal to find the tax amount collected. This is done by dividing the percentage by 100, giving us 0.07. We then multiply the total sales amount by this decimal:
Total sales tax collected = $1,177 × 0.07
Total sales tax collected = $82.39
Therefore, the woman should send $82.39 to the state government for the sales tax she collected.
