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

Answer:
The greatest number of games Elie could have played was 4.
Step-by-step explanation:
This is because if you take 25 and subract the 5.25, you would get 19.75. In order to get the max games Elie could play, you would divide 19.75 by 4, since each game is $4. You would end up with 4.9, but would have to round down since you can't round up.
Answer:
<em>f(50) = 109.44943 feet</em>
Step-by-step explanation:
<u>Modeling</u>
The model of a situation where the skid distance f is measured against the car speed x can be expressed as:
Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:
f(50) = 109.44943 feet
