<h2>Answer:</h2>

The maximum amount you can spend before tax and tip is:

$ 12.397

<h2>Step-by-step explanation:</h2>

x represents the cost before tax and tip.

Also, we have a total of $ 15 to spend on.

The equation which represents the total cost of our meal is given by:

c= x+0.06x+0.15x

This means that:

$c\leq 15\\\\i.e.\\\\x+0.06x+0.15x\leq 15\\\\1.21x\leq 15\\\\x\leq \dfrac{15}{1.21}\\\\x\leq 12.397$

The answer is: $ 12.397

Just solve the equation, x + 0.15x + 0.06x = 15
1.21x = 15,
x = $12.39 (nearly)
