And solving we have:
And we can write the expression like this:
The vertex for this case would be:
And the minimum for the function would be 3 and there is no maximum value for the function
Step-by-step explanation:
For this case we have the following equation given:
We can complete the square like this:
And solving we have:
And we can write the expression like this:
The vertex for this case would be:
And the minimum for the function would be 3 and there is no maximum value for the function
Let n represent the amount Colin earned on Sunday.
On Sat. he earned n/2; on Sun. he earned n; and on Friday he earned (1/2)(n/2).
Then n/2 + n + n/4 = $70
Mult. all terms by 4 to eliminate fractions:
2n + 4n + n = $280
7n = $280 => n = $40
Colin earned n/2, or $20, on Saturday; n, or $40, on Sunday; and n/4, or $10, on Friday.
Note that $20 and $40 and $10 add up to $70, as they must.

Answer:
50 pages per hour
Step-by-step explanation:
25% = 85 / 4 = $21.25 off
5% = 85 / 20 = $4.25
75% = 21.25 • 3 = $63.75
$63.75 + $4.25 = $68
Her total bill was $68
