Question

Three hermit crabs at a pet store cost $ 21.75 . If each hermit crab, h , costs the same amount, which equation can be used to find the cost per hermit crab correctly?

Answer 1

To calculate the cost per hermit crab, use the equation 3h = 21.75 and divide both sides by 3 to solve for h, yielding h = 7.25, which is the cost for one hermit crab.

Step-by-step explanation:

To find the cost per hermit crab, you should set up an equation that represents the total cost for three hermit crabs. Let's denote the cost of each hermit crab as h. Since three hermit crabs cost $21.75, you can represent this scenario with the following equation:

3h = 21.75

To solve for h, the cost per hermit crab, you would divide both sides of the equation by 3:

h = 21.75 / 3

When you divide 21.75 by 3, you will find the cost of one hermit crab:

h = 7.25

Therefore, the equation 3h = 21.75 can be used to find the cost per hermit crab by performing the division as shown above.
