Answer:
$11.10 per gallon.
Step-by-step explanation:
There are 4 quarts in a gallon so the cost of a gallon of oil currently is 1.85×4=$7.40
If the gallon price of oil goes up 50% then our answer is: 7.40×==11.1
The price of oil in March will be $11.10 per gallon.
So we know that 1/5=0.2
Then we take 5/5=1.0
Then we solve 2*1.0=2.0
Now we solve 1/5+1/5+1/5 or 1/5*3=0.6
So then the correct answer is 2.6
Hope this helps!!!
=
A. 2
f(2) =30
f(1)=15
f(n)=f(n-1)*n
Put in n=2
f(2)=f(2-1)*2
= f(1) *2
= 15*2
=30
