Final answer:
To calculate a 15% tip on an $85 service, multiply $85 by 0.15, which equals $12.75. Hence, Lisa would receive a $12.75 tip.
Step-by-step explanation:
The question you've asked is related to calculating a percentage tip for a service provided. Lisa, as a hairdresser, offers a cut and color service for $85. If she receives a 15% tip on the total cost, we need to calculate what 15% of $85 is. To do this, we multiply $85 by 0.15 (which is the decimal equivalent of 15%).
So, the calculation will be:
$85 × 0.15 = $12.75
Therefore, Lisa would receive a $12.75 tip.
