Answer:

$159.95

Step-by-step explanation:

Let price of trumphet be defined by x

price of clarinet = $139.95

Number of clarinets sold = 19

Earning through clarinets' sale = 19*139.95 = 2659.05

Total earning of store = $4578.45

Earning through trumphets' sale = 4578.45 - 2659.05 = 1919.40

price of one trumohet = \frac{1919.40}{12} = 159.95

price of clarinet = $159.95

Which input in this table is incorrect?Cost ofTax onItem Item1.00.082.00 .163.00 .246.00 .5610.00.80Noter all entries are in dol
Norma-Jean [14]

From the table, we can observe that the formula for the total cost of item is

\text{Total cost of item = Cost of item + Tax on item}

From the data in the table, cost of item 6.00 has the input incorrect because the sum of the cost of its item and tax on the item is,

\text{Total cost of item=6.00+56=6.56}

but the total cost was incorrectly inputed as 7.56.

Hence, the correct option is Option A.

Verticalset the denominator of the function equal to zero and solve for 'x', x is the vertical asymptote.Horizontalsubtract the amount of x's in the numerator from the number of x's in the denominator, then do one of the four things to find y: and if the answer is negative, then y=0 does that help any?if the answer is 0, then y= a/b (ax/bx)<span>If the answer is greater than positive 1, then there is no horizontal asymptote
</span>ObliqueIf the answer is 1, then it is oblique. use long division with the denominator as the divisor of the overall function given (not the fraction) and y= ax+/- b 
Does this help at all
