Apet store has 115 fish that need to be placed into fish tanks. each tank hold 6 fish. how many takes does the store need got the fish? a. 19 b. 23 c. 20 d. 21

 (C) 20 is the correct option.

Step-by-step explanation:  Given that a pet store has 115 fish that need to be placed into fish tanks and each tank hold 6 fish.

We are to find the number of tanks that the store need.

We will be using the UNITARY method to solve the given problem.

Number of tanks needed to store 6 fishes = 1.

So, number of tanks needed to store 1 fish will be

Therefore, number of tanks needed to store 115 fishes is given by

Since we cannot have 0.16 tank, so we need one tank more than 19 to store all fishes.

Thus, the store needs 20 tanks for 115 fishes.

Option (C) is CORRECT.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
