Question

The Rattlesnakes football team plays a different opponent every week. So far this season, the Rattlesnakes have won 3 games out of 6. Which equation models the number of consecutive games the Rattlesnakes must win in order to increase their winning percentage to 80%?

Answer 1

The Rattlesnakes must win their next 9 games in order to have an 80% winning percentage.

Hope this helps.

Answer 2

`0.80=(3+x)/(6)`

Explanation:

Given,

The Rattlesnakes have won 3 games out of 6.

So, the ratio of his winning games out of total games =
`(3)/(6)`

Let x be the number of consecutive games the Rattlesnakes must win in order to increase their winning percentage to 80%,

That is,

`(3+x)/(6)=80\%`

`(3+x)/(6)=0.8` ( 1 % = 0.01 )

Which is the required equation.
