Question

Julia is allowed to watch no more than 5 hours of television a week. So far this week, she has watched 1.5 hours. Write and solve an inequality to show how many hours of television Julia can still watch this week.

Answer 1

The inequality is used to solve how many hours of television Julia can still watch this week is
`x + 1.5 \leq 5`

The remaining hours of TV Julia can watch this week can be expressed is 3.5 hours

Solution:

Given that Julia is allowed to watch no more than 5 hours of television a week

So far this week, she has watched 1.5 hours

To find: number of hours Julia can still watch this week

Let "x" be the number of hours Julia can still watch television this week

"no more than 5" means less than or equal to 5 ( ≤ 5 )

Juila has already watched 1.5 hours. So we can add 1.5 hours and number of hours Julia can still watch television this week which is less than or equal to 5 hours

number of hours Julia can still watch television this week + already watched ≤ Total hours Juila can watch

`x + 1.5 \leq5`

Thus the above inequality is used to solve how many hours of television Julia can still watch this week.

Solving the inequality,

`x + 1.5 \leq5\\\\x \leq 5 - 1.5\\\\x \leq 3.5`

Thus Julia still can watch Television for 3.5 hours
