Answer:
there were a total of 55 people at the party.
Step-by-step explanation:
In order to create the equation representing this scenario we first need to represent each step in a formula. Since the total number of people is represented by x we can multiply 3/5 by x and subtract 9 from that. This would then be equal to 24 like so...
3/5x - 9 = 24
Now that we have the formula we can perform opposite operations to isolate x and solve for it.
3/5x - 9 = 24 ... add 9 on both sides
3/5x = 33 ... divide both sides by 3/5
x = 55
Finally, we can see that there were a total of 55 people at the party.
Answer:
$7.2
Step-by-step explanation:
Given data
Weight = 1 1/4
convert to simple fraction= 5/4 pounds
The cost of 5/4 pounds of package = $9
Let us find the cost per pound
cost per pound = 9/5/4
multiply by the multiplicative inverse of the denominator
cost per pound = 9*4/5
cost per pound = 36/5
cost per pound = $7.2 per pound
Hence the cost of 1 pound of the package is $7.2
