1) 2 * (10 * 7 + 7 * 1,25 + 10 * 1,25) = 2 * (70 + 8,75 + 12,5) = 2 * 91,25 = 182,5 square inches - a surface area
2) 182,5 * 0,012 = <span>$</span>2,19 - answer.
5.5% of 2800 =
0.055 * 2800 = 154 <==
Its C, It can't be equal because it is not dividing by 1, It can't be less than 0.4 because if you divide by a decimal the quotient will increase. So the obvious choice is C because it will be greater than 0.4. Also a question for you, why use this website to get answers when there are online calculators....
