A: 80 ft^3
to make math easier, I'm translating the extra inches into a decimal so it's a solid number to represent feet. 9 inches is 0.750, and 1 inch is 0.0833 of a foot.
23.750 x 10.0833 = 239.478375, rounding up to 240 feet^2
multiply this by 0.333 to get the volume needed for the patio, 80 ft^3

(79.92 rounded up to the nearest whole)

B: $530
Multiply the volume of concrete needed by the price per cubic foot.
80 x 6 = $480, and since the volume is less then the limit to surpass the initial cost we add $50 to our total cost, making it $530
