Question of the day :)

• Sofia joined a golf club two years ago. She pays an annual membership fee of $1,045 and a greens fee of $35 each time she plays a game of golf. The function below can be used to calculate the total yearly golfing fee, f (g), in dollars.

f (g) = 1045 + 35g, where g represents the number of times she played golf during the year.

Last year she paid $1,710 as a total golfing fee. For how many games did she pay a greens fee?

$$f(g) = 1045 + 35g$$ 

g = The number of times she played golf during the year. Last year she paid $1,710 as a total golfing fee. Their asking how many games did she pay a greens fee.

You will substitute $1,710 for the "g" in f(g).

$$f(1,710) = 1045 + 35g$$  

You will now subtract 1045 from both sides.
$$f(1,710) = 1045 + 35g$$  
- 1045       - 1045
The 1045 cancels out on the right.

$$f(1,710) =  35g$$ 
-1045

 $$665 = 35g$$
Divide both sides by 35.

$$665/35 = 35g/35$$ 
35 cancels out on the right.
$$19 = g$$
0r
 $$g = 19$$
