Question

Ivan earns $8 each time he walks his neighbors dog. He already walked the dog 5 times.

Answer 1

Answer:

6 times

Step-by-step explanation:

Given: Ivan earns $\ 8$ each time he walks his neighbors dog. He already walked the dog $5$ times.

To Find: How many more times does he need to walk the dog to earn enough money to buy a game that cost $\ 88$.

Solution:

Money earned by the Ivan each time he walk his neighbors dog $=\ 8$

Number of times Ivan already walked the dog $=5$

Money earned by Ivan $=5\times8$

                                      $=\ 40$

Cost of game $=\ 88$

Money required to buy game $=\text{cost of game}-\text{money Ivan has}$

                                                 $=88-40$

                                                 $\ 48$

Let days Ivan need to earn enough money to buy game $=\text{x}$

Money earned by Ivan in $\text{x}$ days $=8\text{x}$

Now,

  $8\text{x}=\ 48$

  $\text{x}=6$

Hence 6 times more Ivan need to walk the dog to earn enough money to buy the game.

Answer 2

Ivan needs to walk the dog 6 more times. 8(5)=40 you subtract 40 from 88 and get 48. 8(6) is 48. When Ivan walks the dog 6 times he will earn 48. 48+40 is 88.
