In three months, Harold watched a total of 40 movies. If he watched 12 movies in June and 13 movies in July, how many movies did he watched in august? Use the variable a to model ur work.

Answer 1

To find out how many movies Harold watched in August, we can set up an equation using the given information.

Let \( a \) represent the number of movies Harold watched in August.

From the problem, we know:

• Movies watched in June: 12
• Movies watched in July: 13
• Total movies watched in three months: 40

We can express the total number of movies watched over the three months as:

\[ 12 + 13 + a = 40 \]

Now, we can simplify this equation:

\[ 25 + a = 40 \]

Next, we solve for \( a \) by subtracting 25 from both sides:

\[ a = 40 - 25 \] \[ a = 15 \]

Therefore, Harold watched 15 movies in August.
