$ 325.2372 will be charged on Patrick's Visa card.
Explanation
The regular price of each tire is $95.99 and the discount amount is $20 per tire.
So, the selling price of each tire will be: [tex](95.99-20)dollar=75.99 dollar[/tex]
and the total selling price of 4 tires [tex]= (75.99*4)dollar=303.96 dollar[/tex]
The sale tax is 7%. So, the amount of sale tax [tex]= 7\% of 303.96 = (0.07*303.96)dollar = 21.2772[/tex] dollar
So, the total charge on Patrick's Visa card will be: [tex](303.96+21.2772)dollar = 325.2372[/tex] dollar
