<span>The question is asking us to calculate the final cost of the item after the tax is applied. The price of item before the tax is: P = $40 and the tax rate as a percent is 8%. It means that r = 0.08. And the formula is: C = P * ( 1 + r ). Finally: C = $40 * ( 1 + 0.08 ) = $40 * 1.08 = $43.20. Answer: The final cost is $43.20. </span>
Answer:
Step-by-step explanation:
Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.
Set up a system of equations:
Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":
Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:
Answer:
The fraction that represents the decimal 0.12 is 3/25
Step-by-step explanation:
step 1: find the place value of the last digit in 0.12
Since they are 2 digits in 0.12 the place value of last digit is the 100 th, therefore 0.12 is the same as 12/100
step 2: simplify 12/100 by dividing both the denominator and numerator by 4
that is <u>1</u><em><u>2 divide by 4 = 3 and 100 divide by 4 =25</u></em>
therefore the fraction = 3/25
3x=40.20.... Each book costed $13.40
0.1111 if you want it as a decimal
