Question

Caroline's piano teacher suggest that she practice at least 225 minutes per week Caroline plants to practice five nights each week right and inequality to describe the situation then complete the sentence

Answer 1

`m \ge 45`

She must practice for at least 45 minutes each night

Explanation:

Given

`Practice = 225\ minutes` --- at least

`Nights = 5` --- each week

Required

Write an inequality

Let the number of minutes in a night be m.

At least means
`\ge`

So, we have:

`Nights * m \ge Practice`

`5* m \ge 225`

Divide both sides by 5

`m \ge 45`
