Answer:
A= -u²n²t²s²arme²
Step-by-step explanation:
Evaluate m, then set it equal to 15.
=15
Evaluate s, the set it equal to 2.
=2
Simplify unitsareminutes.
−u²n²t²s²arme²
List all the solutions.
BN•N=BN²
m=15 ==15
s=2 2==2
Add n on both sides:
3m = km - 8 + n
Subtract km on both sides:
3m - km = n - 8
Factor the Left-Hand Side:
m(3 - k) = n - 8
Divide both sides by (3 - k):
m = (n - 8) / (3 - k)
Answer:
Total cost = $13.96
Step-by-step explanation:
The total to be paid for the item is the addition of its price plus the taxes. That is:
![Total\,\,cost=13.42+0.04\,*\,13.42\\Total\,\,cost=13.42+0.5368\\Total\,\,cost==13.9568](https://tex.z-dn.net/?f=Total%5C%2C%5C%2Ccost%3D13.42%2B0.04%5C%2C%2A%5C%2C13.42%5C%5CTotal%5C%2C%5C%2Ccost%3D13.42%2B0.5368%5C%5CTotal%5C%2C%5C%2Ccost%3D%3D13.9568)
Which can be rounded to $13.96
