Each day, you take vocal lessons for $v$ minutes and trumpet lessons for 30 minutes. Write and simplify an expression to find how many minutes of lessons you take in 4 days.

The total minutes of lessons I take in 4 days =

Step-by-step explanation:

Given:

Minutes of vocal lessons I take each day =

Minutes of trumpet lessons I take each day = 30

To write and simplify how many minutes of lessons I take in 4 days.

Solution:

Total number of minutes of lesson I take each day can be calculated by adding the minutes of lessons taken each day and can be given as:

⇒

Using unitary method:

If each day I take minutes of lessons.

So, in 4 days I will take = minutes.

Simplifying using distribution :

⇒

Thus, total minutes of lessons I take in 4 days =
