  1. Tickets for a concert have been in incredibly high demand, and as the date for the concert draws closer, the price of tickets increases exponentially. The cost of a pair of concert tickets was $150 yesterday, and today it is $162. As you complete parts (a) through (c) below, assume that each day’s percent increase from the day before is the same. Homework Help ✎

    1. What is the daily percent rate of increase? What is the multiplier?

    2. What will be the cost of a pair of concert tickets one week from now?

    3. What was the cost of a pair of tickets two weeks ago?

What percent of $150 is $162?

Construct a table of values or an equation describing the relation between the number of days since yesterday and the price of a ticket.

In order to go backwards, make the exponent negative.
