Question

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

How many more times does he need to walk the dog to earn enough money to buy a game that cost $88?

Answer 1

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.

Answer 2

6 times

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*8`

`=\$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.
