Answer:
$15.17
Step-by-step explanation:
First we calculate the value for the sales tax:

we then add the value for the sales tax ($1.07) to the initial bill:

We were instructed to calculate the tip after the sales tax was added so:

after we will add the value for the tip to the value that we have for the bill ( this is the new value that includes the sales tax) to find the total cost:

<em>Therefore</em><em> </em><em>the</em><em> </em><em>total</em><em> </em><em>cost</em><em> </em><em>for</em><em> </em><em>his</em><em> </em><em>mean</em><em> </em><em>is</em><em> </em><em>$</em><em>15.17</em>
5:7 (pencils to pens)
7/12 chance that a pen from the first box will be selected.
4:4 (colour pencils to crayons)
4/8 = 1/2 chance that a crayon from the second box will be selected.
The probability of picking both:
7/12 * 1/2 = 8/24 = 1/3
Answer:
The equation is:
An identity
Has infinitely many solutions
No solution
Step-by-step explanation:
Because there is integers on both sides, we know that any attempts to fix this will either cause an identity, or a false numerical equation(an identity but <em>w r o n g</em>).(Note, an identity can either mean 2 = 2 or x = x).
Identities have infinite solutions, because it does not matter what you put in, the equation will always be true. False equations do not have a solution because they aren't even true equations.
Hope this helps!
Answer:
15% off
Step-by-step explanation:
We know we paid $25.50 of the original $30. We can divide these two numbers
. This is means we paid 85% of the original price. The discount percentage is the remaining percentage from 85 to 100 which is 15. The pants were 15% off.
