The right answer is Option D: S>$300,000.
Step-by-step explanation:
Given,
Base salary of Alan = $18000
Commission = 9% = 
Amount Alan wants to earn = $45000 or more
Let,
s be the worth he needs to sell.
Therefore,
Base salary + Commission*Total sales>Amount Alan wants to earn
18000+0.09s>45000

Dividing both sides by 0.09

Alan must sold items that worth at least $300,000.
The right answer is Option D: S>$300,000.

X is the number of dog
y is the number of cats , y=40
25% of x is 25*x /100=25x/100=x/4
<span>and there are 25% more cats than dogs means y+ x/4=x implies 40=(3/4)x
</span>x=160/3=53
so the number of dogs is 53 and the number of cats is 40
the total number is 53+40=93
This is the concept algebra.
Volume of of paint that is required to paint large shipping crate is a liters.
suppose the volume of this crate is x cubic units.
The volume of the next crate to be painted will be 2x cubic units.
Hence the amount of paint required to paint the crate will be:
(volume of bigger crate)/(volume of smaller crate)×(volume of liters required to paint the first crate)
=(2x)/(x)×a
=2a liters
To paint the new crate 2a liters of oil is needed.
