Chapter 1: Q9. (page 57)

Gridded Response Evaluate the expression $5 \cdot d when d = 6$ to find the cost (in dollars) of buying 6 posters when each poster costs $5.

Short Answer

Expert verified

The cost of buying 6 posters is $30.

Step by step solution

Step-1 – Apply the concept of product

When two or more numbers are multiplied together, it gives a number. The numbers that are multiplied, are called the factors. And the result of the multiplication of numbers is called the product of those numbers.

Step-2 – Example for the product

In the product $2 \cdot 3 \cdot 4 = 24$ , the numbers 2, 3, and 4 are being multiplied to give the product 24. So, the numbers 2, 3, and 4 are the factors in this equation and 24 is the product of the numbers.

Step-3 – Evaluate the expression

To evaluate the expression $5 \cdot d$ , substitute the value of d as 6 and multiply the numbers as shown below,

$\begin{matrix} 5 \cdot d = 5 \cdot 6 \\ = 30 \end{matrix}$

Thus, the cost of buying 6 posters is $30.
