6-49.

Write an equation to represent each of the situations described below.

1. On Friday, $150$ people went to see “Ode to Algebra” performed in the school auditorium. Both $c$ children and $a$ adults attended the performance.

We know that a total of $150$ people attended the Ode to Algebra. There were two main groups of people
(the children and the adults) so: $(150 − c)$ yields the amount of adults.

2. The cost of a new CD is $$14.95$, and the cost of a video game is$$39.99$. Wade spent \$$84.84$ on $c$ CDs and $v$ video games.

Refer to part (a) for help. Use what you know about the problem to create a logical expression.
