To find: the number of scarves R can make

Answer to Problem 36SGR
R can make 7 scarves if she has 336 inches of material.
Explanation of Solution
Given:
R has 336 inches of material.
Each scarf requires 48 inches of material
Calculation:
The objective of the problem is to find the number of scarves R can make.
Let the number of scarves R can make be x.
It is given that each scarf requires 48 inches of material.
R has 336 inches of material.
So,
Dividing both side with 48
To check the solution, put the value of x in the given equation.
Hence, R can make 7 scarves if she has 336 inches of material.
Conclusion:
Hence, R can make 7 scarves if she has 336 inches of material.
