Given:
The total cost of the order is
where, T is the total cost, b is the number of bath towels, and w is the number of wash cloths.
Her budget is $85.

We have,
Her budget is $85. So, total cost is less than or equal to 85.
...(i)
For maximum number of bath towels, the number of wash cloths is 0.
Divide both sides by 6.
For maximum number of wash cloths, the number of bath towels is 0.
Divide both sides by 2.
Therefore, the required constraints for maximum of washcloths or bath towels are and
respectively.
