Answer:
4.625 gallons
Step-by-step explanation:
1. 11 pints plus 13 quarts is 18.5 quarts
2. 18.5 quarts is equal to 4.625 gallons
Remember
a²-b²=(a-b)(a+b)
8x²-50y²
2(4x²-25y²)
(2)([2x]²-[5y]²)
2(2x-5y)(2x+5y)
First you need to find the amount for each of the items, then total it up:
T-shirts> 9.50 x 2 = 19
Socks> 7.95 x 3 = 23.85
Shoes> 49.95
Total: 19 + 23.85 + 49.95 = $92.80
Next find the tax:
(to find the taxes you multiply the total by the percent)
92.8 x 0.06 = 5.57
-- then add the amount to your item total
92.8 + 5.57 = 98.37
~OR~
You could multiply the item total by 1.06 so that you wouldn't have to add to taxes to the previous total because it is already part of the equation
92.8 x 1.06 = 98.37
