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 first step for solving this expression is to write the division as a fraction.
x +

× x
Calculate the product.

Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:

Now multiply the terms with the same base by adding their exponents.

Finally,, add the numbers together to get your final answer.
x +

Answer:
800 months
Step-by-step explanation:
The formula for interest is:
(Capital * saving account * time) / 100
So:
(10000 * 0.06 * x) / (100) = 4800
We clear x:
(10000 * 0.06 * x) = (100) * 4800
x = 480,000 / (10000 * 0.06)
x = 800 months (66.67 years)
Answer:
{-11, -9, -7, -5, -3}
Step-by-step explanation:
Put each domain value into the function to find the corresponding range value. The range is the list of all of those values.
__
range = f(domain)
= 2{-2, -1, 0, 1, 2} -7 = {-4, -2, 0, 2, 4} -7
= {-11, -9, -7, -5, -3} . . . . . the range for the given domain
