Answer:
The number of weekday hours are 5.
Step-by-step explanation:
<em>Let the number of weekday hours be "x".</em>
<em>The total week hours are 26, then number of weekend hours is (26-x) .</em>
<em>The charges for weekdays are $2 per hour and for weekends $10 per hour.</em>
The total money spent is $220.
x = 5.
Thus weekday hours utilized are 5 hours, and weekend are (26-5) 21 hours.
4 is the proportion because 8 + 4 is 12 then keep adding 12 + 4 = 16 + 4 = 20 So that mean it is proportional I hope that helps.
The instructor wants the profit to be positive, so

n - 400/70 > 0
n > 5 5/7
