Answer:
c. $28
Explanation:
If Emily only has $30 to spend and the sales tax is 5%, then we can set up an equation to solve for the maximum cost of the dress:
30 = x + 0.05x
where x is the cost of the dress.
Simplifying this equation gives:
30 = 1.05x
Dividing both sides by 1.05 gives:
x = 28.57
Therefore, the maximum cost of the dress is approximately $28.57.
So the answer is © $28.
