Ramona went out with her 3 sisters, they spent $58 plus

Leto [7]

<h2>Problem:</h2>

Ramona went out with her 3 sisters, they spent $58 plus 9% tax on their meal. They also left 15% tip. If they divided up the bill evenly, how much did each of them spend?

<h2>Solution:</h2>

$\frac{58 + 58(9\% + 15\%)}{3}$

$= \frac{58 + 58(0.09 + 0.15)}{3}$

$= \frac{58 + 58 \times 0.24}{3}$

$= \frac{58 + 13.92}{3}$

$= \frac{71.92}{3}$

$= 23.97$

<h2>Answer:</h2>

Each of them did spend $23.97
