Answer:
$400
Step-by-step explanation:
Let the initial total cost be represented = $X.
Hence, for 20 family members
= $ x/20 each .......1
Now that they are 25 members
= $x/25 each.......2
Each in the original group which is equation 1 owed $4 less.
That is,
x/20 - 4 ........ 3
Now equate 2 and 3
X/20 - 4/1 = X/25
Taking the LCM of both sides
X-80/20 = X/25
Cross multiply both sides
25( x-80 ) = 20x
25x-2000 = 20x
Collecting like terms
25x-20x = 2000
5x = 2000
Divide through by 5
X = 2000/5
X = 400
The total cost for the catered meal is $400.
To check if it was correct
Put 400 into equation 1 and 2 and then minus whatever you get from each other, you will get $4
From equation 1
400/20 = $20
From equation 2
400/25 =$16
$20-$16 = $4

Answer:
1/4, 5/9, 9/10, 99/100
Step-by-step explanation:
<u>Step 1: Make common denominators</u>
The common denominator is: 900
<u>Step 2: Make sure they all have common denominator</u>
5/9 * 100/100 = 500/900
99/100 * 9/9 = 891/900
1/4 * 225/225 = 225/900
9/10 * 90/90 = 810/900
<u>Step 3: Order the fraction from smallest to largest</u>
225/900, 500/900, 810/900, 891/900
<u>Step 4: Check to see what the original values were</u>
1/4, 5/9, 9/10, 99/100
Answer: 1/4, 5/9, 9/10, 99/100
