Answer:
7 hours
Step-by-step explanation:
Hello!
Since both expressions are equal to each n, we can set the other halves of the expression equal to each other.
Solve for h:
- n = 9h + 26
n = 12h + 5 - n = n
9h + 26 = 12h + 5 - 9h + 26 = 12h + 5
- 26 = 3h + 5
- 21 = 3h
- h = 7
Michael will take 7 hours. Now that we know this, we can plug in 7 for "h" to solve for "n", the number of newspapers sold. Im going to use the first equation
Sove for n:
- n = 9h + 26
- n = 9(7) + 26
- n = 63 + 26
- n = 89
89 newspapers were sold.
The answer is 7 hours.
