Answer:
n must be 27
Step-by-step explanation:
Let this number be x. Then -6(n - 12) = -90.
Dividing both sides by -6 yields n - 12 = 15.
Add 12 to both sides.
Then n must be 27.
Check: subtract 12 from 27; this yields 15. Now multiply this result by -6. The result is -90, which was expected.
Since this is part C, we're gonna need more information than that because we don't have your exact homework! Maybe reupload ? I would need the calculations for the cost of bracelets and how much were sold to see the break even point to be accurate!
