To calculate: The amount to buy 18 yards of the fabric by drama department.
Answer to Problem 4E
The amount to buy 18 yards of the fabric by drama department is
Explanation of Solution
Given information:
Per yard fabric cost is
Formula used:
Four step plan is used to solve situations with help ofmathematical tools.
First understand the situation. Plan the solution according to it then solve it using mathematical tools and at last verify your solution.
Calculation:
It is provided that the per yard fabric cost is
An estimated answer is required for the problem as cost in dollars is to be evaluated and money can be easily returned back.
Total cost is per yard cost multiplied by total length of fabric needed.
Denote total cost by C ,
Therefore,
Round off the result to nearest tenth, to obtain cost,
Since, the total cost is positive number, the answer is verified.
Thus, the amount to buy 18 yards of the fabric by drama department is
