Number 19 I think is if you add the awnser to one of the numbers you where subtracting and you get the other number you where subtracting you are right like...

Lets say you had the problem 3-2 which is obviously 1 but if you did 2+1 it's 3 so that's how you check.

$ 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: $(95.99-20)dollar=75.99 dollar$

and the total selling price of 4 tires $= (75.99*4)dollar=303.96 dollar$

The sale tax is 7%. So, the amount of sale tax $= 7\% of 303.96 = (0.07*303.96)dollar = 21.2772$ dollar

So, the total charge on Patrick's Visa card will be: $(303.96+21.2772)dollar = 325.2372$ dollar
