Chapter 1.4, Problem 41IP

To determine

Write an expression that represents the total cost of clay, in dollars, for the activity.

Answer to Problem 41IP

  $\text{C = \$ 114}·\text{b}$

Explanation of Solution

Given:

A ceramics class needs to buy blocks of clay for an activity. Use the table at the right to write an expression that represents the total cost of clay, in dollars, for the activity. Simplify the expression.

Number of students = 19 and blocks of clay per student is b and Cost per block = $6.

Concept Used:

Number of students = 19 and blocks of clay per student is b and Cost per block = $6.

Calculation:

Number of students = 19 and blocks of clay per student is b.

Total number of blocks needed = $19·\text{b}$

Cost per block = $6.

Total cost of ( $19·\text{b}$ ) blocks is $\text{C}=\$6(19·\text{b)}\text{= \$ 114}·\text{b}$

Thus, Total cost of ( $19·\text{b}$ ) blocks is $\text{C}=\$6(19·\text{b)}\text{= \$ 114}·\text{b}$
