Don purchased software for $99.95. How much tax was
charged if the tax rate was 9.5%?

9.49525

Step-by-step explanation:

You have the total and the percent so you are looking for the part. You can set up a proportion with 9.5 over 100 and x over 99.95. Then you multiply 9.5 times 99.95 to get 949.525 which then you divide by 100. So x is 9.49525

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
