Three different golfers played a different number of holes today. Rory played 9 holes and had a total of 42 strokes. Alicia play

choli [55]

Answer:

Alicia is the golfer who has had the lowest number of strokes per hole

Step-by-step explanation:

we know that

The unit rate of the number of strokes per hole is equal to divide the number of strokes by the number of holes

Let

x ----> the number of strokes

y ----> the number of holes

we have

Roy

$x=42\ strokes\\y=9\ holes$

$\frac{x}{y}=\frac{42}{9}=4.67\ strokes\ per\ hole$

Alicia

$x=79\ strokes\\y=18\ holes$

$\frac{x}{y}=\frac{79}{18}=4.39\ strokes\ per\ hole$

Rickie

$x=123\ strokes\\y=27\ holes$

$\frac{x}{y}=\frac{123}{27}=4.56\ strokes\ per\ hole$

Compare

4.39 < 4.56 < 4.67

therefore

Alicia is the golfer who has had the lowest number of strokes per hole
