Question

Karina needs a total score of at least 627 on three games of CA bowling to break the league record. Suppose she bowls 222 on her first game and 194 on her second game. What score does she need on her third game to break the record?

Answer 1

See the solution process below:

Explanation:

First, let's call the score she needs in the third game `s`.

The total score or the sum of the three games must be at least 627 and we know the score of the first two games so we can write:

`222 + 194 + s >= 627`

Solving for `s` gives:

`416 + s >= 627`

`-color(red)(416) + 416 + s >= -color(red)(416) + 627`

`0 + s >= 211`

`s >= 211`

For Karina to have a total score of at least 627 the third game must be a 211 or higher.
