Brandon buys a radio for $46.49 in a state where the sales tax is 7%.

I couldb't understand you're question but here are possible answers and explanations

What is the total price: $49.74

$46.49 • 0.07 = 3.25

46.49 + 3.25 = 49.74

What was the sales tax amount: 3.25

$46.49 • 0.07 = 3.25

Hope this helps.

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

the answer is 62.8 cubic units
