Question

malik bought five shampoo bottles. he paid $3.00 as tax for all five bottles and knows the tax rate is 4%. calculate the price of a bottle of shampoo before tax.

Explanation:

Step1: Find total price before tax for 5 bottles

Let \( T \) be total price before tax for 5 bottles. Tax rate \( r = 4\%=0.04 \), tax amount \( t = 3 \). We know \( t = r\times T \), so \( T=\frac{t}{r} \).
\( T=\frac{3}{0.04}=75 \)

Step2: Find price per bottle

Total price for 5 bottles before tax is 75, so price per bottle \( p=\frac{75}{5} \).
\( p = 15 \)

Answer:

The price of a bottle of shampoo before tax is \$15.
