I need help on my math homework.A hairdresser is considering ordering a certain shampoo. Company A charges $4 per 8-oz bottle plus a $10 handling fee per order. Company B charges $3 per 8-oz bottle plus a $25 handling fee per order. How many bottles must the hair dresser buy to justify using Company B? (Answer in a complete sentence.)
I don't know what justify using company B means. Can someone help me?
Answers
let x= the number of bottles the customers buys
first, lets consider how many bottles the customer must buy for the price to be the same no matter which company.
4x+10=3x+25

.
x=15, so at 15 bottles, the cost is the same for either company. At this point you look at x=16, one bottle higher, to compare costs, seeing that for company A this is $74 while for company B this is $73, so at 16 bottles company B is cheaper

Answer:
The number of parts on the four plots are 40.5
Step-by-step explanation:
The number of plots is 4 and each has an area of 12 acres, thus the total area is 36 acres.
Dividing them into a number, n, of parts gives;
where n is the number of parts.
=
of an acre
Thus,
n = (36 × 9) acres ÷ 8 acres
= 324 ÷ 8
= 40.5
Thus it has been divided into 40.5 parts.

Why do we need to find least common denominator?
It is because summing(or subtracting) fractions with common denominators is very easy as compared to those with unlike denominators.
When denominators are same, the sum or subtraction operation can directly work on the numerator values and their result will be putted on top of the denominator.
For example:
The least common denominator of 10 and 6 is 30 since:
6 , 12, 18, 24, 30
10, 20, 30
The least number that is common in both 6's and 10's multiple's list is 30.
Rewriting both the fractions using least common denominator:
and
Since both the new fractions are of same value as of old pair, thus their sum would be same, as shown here:
Thus, the pair of fractions needed are and
