Step-by-step explanation:
Answer:
8 people in the original group.
Step-by-step explanation:
Let x be the number of people who were originally present for the dinner that cost $160. Their average cost per person would be:
$160/x
If 2 more people join, there are x+2 people. Ignoring the awkward situation that they apparently did not order any additional food, they agree to share the cost of the dinner. The average cost is now:
$160/(x+2)
We are told that this new average is now $4 less per person.
$160/(x+2) = ($160/x) - $4
$160 = (($160/x) - $4)(x+2)
x = 8 people

Look below for answer! Have a great day and please mark me brainliest!
Step-by-step explanation:
Bedroom 1: 22x15=330
330x7.25=2392.5
Bedroom 2: 15x12=180
180x7.25=1305
Bedroom 3: 13x12=156
156x7.25=1131
2392.5+1305+1131= 4828.5
Bedroom 1: 22x15=330
330x6.75=2227.5
Bedroom 2: 15x12=180
180x6.75=1215
Bedroom 3: 13x12=156
156x6.75=1053
2227.5+1215+1053+100= 4595.5
Therefore, 6.75 per square foot plus a $100 fixed installation fee would be the cheapest.
12 students went to math because 1/8 would be 6 and you would just add another eighth, which would be 12.
