Question

Help! Can some one explain Jessica has her hair styled and wants to tip her hair stylist 18%. Write an
equation that could be used to calculate the tip, y, for a bill of x dollars.

Answer 1

Answer:

y = .18x

Step-by-step explanation:

The tip is going to be 18% of what she payed, and this says that x is what she payed. That means you can write it as:

tip = 18% of bill

y = 18% of x

18% of x an be written as .18x in decimal, so:

y = .18x
