I couldn't find anyone that led to the answer 20 but the one that ended closest to 20 is the last one.
Answer:
$130
Step-by-step explanation:
If Nathan already has $90 then you would add the amount of money collected after the 4 weeks. In each week he makes $10.
The equation would be $90+($10x4)= $X
If the width is 28 inches, then divide that by 4 and you get 7. You multiply that by 5 to get the length. That would be 35. Just to check, you know that the width 28 and length 35 are in ratio 4:5 if you divide by 7. The perimeter would be 2(35+28)=63*2=126. So the perimeter is 126. The area would be 35*28 which is 980. To sum up, the answers are as follows.
Length: 35 in
Perimeter: 126 in
Area: 980 inches squared.
200+50+4 I think is the answer
972 / 3 = $324
Which means that each person will pay $324
