Answer: $48
Step-by-step explanation:
From the question, we are told that in Michigan, the sales tax rate is 6% and that an item costs $50.88 including tax.
Let the cost of the item before tax be x. This means that x plus 6% of x equals to $50.88. This can be mathematically expressed as:
x + (6% of x) = $50.88
x + (6/100 × x) = $50.88
x + (0.06 × x) = $50.88
x + 0.06x = $50.88
1.06x = $50.88
When then divide by the coefficient of x
1.06x/1.06 = #50.88/1.06
x = $48
The price before the tax is $48

The answer I got was The third one
The solution of the function is - cos t - ¹/₄cos 2t + c.
<h3>What is the indefinite integral?</h3>
An indefinite integral is a function that practices the antiderivative of another function.
It can be visually represented as an integral symbol, a function, and then a dx at the end.
The given function is;
Multiply by sint in the function and simplify;
Use trigonometric formulas for double angles:
Substitute the values in the function
And now we integrate this trigonometric form.
Hence, the solution of the given function is - cos t - ¹/₄cos 2t + c.
