A: To find the rate in feet per minute, we can use the information given.
Every two minutes, the submarine dives 300 feet. So
.
In order to confirm that our rate is correct, we can use the second set of information given.
=
.
Since we know that the rate is 150 feet per minute, we can multiply it by any number of minutes and get the answer of how deep the submarine is. We can use a variable x to represent the number of minutes and y to represent the depth in feet.
There's our equation.
B: It would be more reasonable to use an equation with the rate feet per minute because it is more accurate since the time interval isn't too big.

Division is one of the basic mathematical operations. The cost of Brand A and B is the same.
<h3>What is division?</h3>The division is one of the most basic arithmetic operations. It is used to find the number of times a number is been added to itself.
Given to us
Brand A: 14 ounces for $44.66
Brand B: 20 ounces for $63.80
To compare the two brands we will find the cost of one ounce for each brand.
For Brand A,
The cost of 14 ounces is $44.66, therefore,
For Brand B,
The cost of 20 ounces is $63.80, therefore,
From the above two values, we can conclude that the cost of Brand A and B is the same.
