Question

Naomi is a songwriter who collects royalties on her songs whenever they are played in

Answer 1

Equations can be solved in several ways; one of these ways is the graphical method.

The number of commercials, x, and  the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.

Let:

$x \to$  commercials

$y \to$ movies

She earned a total of $300.

This is represented as:

$20x + 100y =300$

Her songs were played on 3 more commercials than movies.

This is represented as:

$x = 3 + y$

See attachment for the graphs of

$20x + 100y =300$

$x = 3 + y$

From the graph, the lines of both equations intersect at:

$x = 5$

$y = 2$

This means that:

• The number of movies is 2
• The number of commercials is 5
