$14.25 is the total answer. Take $42.75 and divide it by 3.
<span>For more difficult cases, it may be easier to draw the graph first using the domain if possible and then determine the range graphically.See if you can find the inverse function. The domain of a function's inverse function is equal to that function's range.<span>Check to see if the function repeats.</span></span>
Take 4,000 times 12 to get 48,000. that’s how much A costs.
B is a little harder. you have to take (2,300+300)x12+(4*250). this equals $32,100
the correct answer would be B.
Song A has 1 .10 beats/second and song B has 1.16 beats/second so it is song a.
