Question
Matthew needs to practice piano for at least 30 hours every 4 weeks.
He has practices 8 hours a week for the last 3 weeks.
He practiced 10 hours this week.

Matthew says that 3 x 8 is less than 30 so he has not practiced enough during the 4 weeks.

Is Matthew correct?(1 point)
Responses

yes, 3 x 8 = 24 and 24 < 30
yes, 3 x 8 = 24 and 24 < 30

No; Matthew should have multiplied 4 x 8 = 32 and 32 > 30
No; Matthew should have multiplied 4 x 8 = 32 and 32 > 30

No; Matthew should have multiplied 3 x 10 = 30 and 30 = 30
No; Matthew should have multiplied 3 x 10 = 30 and 30 = 30

No; Matthew did not add 10 hours from the last week. It should be 3 x 8 = 24 and 24 + 10 = 34 and 34 > 30

Answer 1

To determine whether Matthew has practiced enough, we can break down the situation:

1. Matthew practices 8 hours a week for the first 3 weeks: \[ 3 \times 8 = 24 \text{ hours} \]

2. In the fourth week, he practiced 10 hours.

3. To find the total practice hours over the 4 weeks, we add those two amounts together: \[ 24 + 10 = 34 \text{ hours} \]

Now we compare this with the required practice of 30 hours every 4 weeks: \[ 34 > 30 \]

So, Matthew has practiced enough.

The correct response is: No; Matthew did not add 10 hours from the last week. It should be 3 x 8 = 24 and 24 + 10 = 34 and 34 > 30.
