B-55.

For each problem, write one or two equations to represent the situation and then solve. Be sure to define your variable(s) and clearly answer the question.

1. At the farmer’s market Laura bought three pounds of heirloom tomatoes.
If the tomatoes are priced at $8$ for five pounds, what did Laura pay for her tomatoes?

This problem can be solved using a proportion.

1. Adult tickets for the school play cost $5$ and student tickets cost $3$. Thirty more student tickets were sold than adult tickets. If $1770$ was collected, how many of each type of ticket were sold?

Let $a =$ # adult tickets and let $s =$ # student tickets

$3s + 5a = 1770$
$s = a + 30$
