It’s A. $25.20
You find the rate you dividing the cost ($18) by how many gallons (5). Then you multiply by what you are looking for (7 gallons). You get 25.20.
To find square numbers, you multiply the number by itself.
For example:
5 x 5 = 25
10 x 10 = 100
I believe the answer would be -2 and -11 hope this helped!
