Answer:

15

Step-by-step explanation:

3+1+3+1+3+1+3= 15 this is what it would look like if you write it out. To save time do 3 times 4 to get 12 and then just add three ones to 12 to get 15.

Answer:

32 goldfish

Step-by-step explanation:

Given:

  • Number of fish tanks = 8
  • Volume of water per fish tank = 5,544 in³
  • Water required by 1 goldfish = min 1,386 in³

Number of fish per tank = water per tank ÷ water per goldfish

                                        = 5544 ÷ 1386

                                        = 4

Therefore, each tank can hold a maximum of 4 goldfish.

Greatest number of goldfish = number of tanks × fish per tank

                                               = 8 × 4

                                               = 32
