Guys but to your i got a 100 on my homework yesterday .

Easy peasy
1.
d=number of dudes
l=number of ladies
total is 55 so
d+l=55

total cost is 75 so
2d+l=75
multiply first eeuqaiton by -1 and add to second

2d+l=75
-d-l=-55 +
d+0=20

d=20
sub
d+l=55
20+l=55
l=35
35 ladies

2.
ratio and proportion
$87 is to 8 as is $x is to 5
87/8=x/5
times both sides by 5
435/8=x
use calculator
54.375=x
round
$54.38 recieved

3.
around the edge
means perimiter
disregard how deep the pool is

60 feet long
x wide
P=2(L+W)
P=220
220=2(60+x)
divide 2
110=60+x
minus 60 both sides
50=x
it has to be 50 feet wide

4. monthly over 5 years
1 year=12 months
12 times 5=60 months
12381/60=206.35 per month
$206.35

5.
total-food-gas-utilities=left
1624-256-125-150=1093 left
you should be able to do this one no problem
$1093 let

1. 35 ladies
2. $54.38
3. 50 feet
4. $206.35
