Step-by-step explanation:
∩
is asking for the intersection of sets
and
, or simply, which numbers can be found in both sets.
The numbers shared between the two sets are .
Next, we need to union this result with the set , or simply, combine the numbers in both sets together.
This would result in
Answer:
C. Gas Station A sells gasoline at a lower rate. Its price is $3.05 per gallon
Step-by-step explanation:
To answer this, all you need to do is first figure out how much per gallon each of the gas stations offer.
Because Gas station B is practically given to you by the equation, I'll show you how to interpret it:
p = $3.08g
p is the price
g is the gallon
So the price you will pay will be $3.08 times the number of gallons. This means that 1 gallon, if you substitute it will be $3.08.
This would eliminate options A and B.
Now to figure out how much Gas station A charges, just choose one of the prices. All we need to do is to divide the price given by the number of gallons:
So Gas station A is lower than Gas station B.
