When going to the local swimming pool, you will pay $9 per person and $3 for parking. if y represent the total cost and x represents the number of persons, what is the function rule that describes this pattern?

a. y = 9x + 3
b. y = 9x – 3
c. y = –9x + 3
d. y = –9x – 3

S = 380 - 380*80%

Step-by-step explanation:

Given:

So, the new price of the desk after discounting is:

380(100% - 20%)

= 380*80%

= 304$

The amount of money saved: 380 - 304 = 76$

Hence, the equation can be used to determine the amount of money saved is:

Saving = 380 - 380*80%

Hope it will find you well.
