Answer:
Step-by-step explanation:
You must state the "price before tax". Let this be P. Also, you must state the sales tax rate. Let this be r, where r is a decimal fraction.
Then the sales tax is rP, the product of the tax rate and the "price before tax."
The total cost of the item (for which it is sold) is (P + rP)($40).
If P = $40 and the sales tax rate is 7%, then
this total cost is (1 + 0.07)P = 1.07P = $42.80
Your question would be clearer if you wrote it like this: Given that the base price of an item is $40 and that the sales tax rate is 7%, find the total cost of the item with tax. That would be (1 + 0.07)($40), or $42.80.
The sales tax is $42.80 - $40 = $2.80.
Answer:
the answer is b
Step-by-step explanation:
7pi / 4
Answer:
No solution
Step-by-step explanation:
To solve the equation, we would have to find the value of m that would make the equality true.
3(m - 1) = 5m + 3 - 2m
Distribute the 3 on the left side.
3m - 3 = 5m + 3 - 2m
Combine like terms on right side.
3m - 3 = 3m + 3
Add 3 to both sides.
3m = 3m + 6
Subtract 3m from both sides.
0 = 6
Since 0 does not equal 6, there would be no solution to the equation, since no value of m would make 0 = 6 true.
I hope you find my answer and explanation to be helpful. Happy studying.
If both C and D equal 15 then the answer is 105.
