Solve the following problem. See Example.

TRUCKING An automobile transport is loaded with 9 new Chevrolet Malibu sedans, each valued at $21,605. What is the total value of the cars carried by the transport?

Example

Table Settings One place setting like that shown on the right costs $94. What is the total cost to purchase these place settings for a restaurant that seats 115 people?

Analyze At this stage, it is helpful to list the given facts and what you are to find.

Form The key word total suggests addition. In this case, the total cost to purchase the place settings is the sum of one hundred fifteen 94’s. This repeated addition can be calculated more simply by multiplication.

We begin with a verbal model (shown in blue) that describes the situation in words. Then we translate the words to numbers and symbols.

Calculate Use vertical form to perform the multiplication:

State It will cost $10,810 to purchase 115 place settings.

Check We can estimate to check the result. If we use $100 to approximate the cost of one place setting, then the cost of 115 place settings is about 115 ? $100 or $11,500. Since the estimate, $11,500, and the result, $10,810, are close, the result seems reasonable.
