This can be done easily in a few ways. One, you could do equivelent fractions as this. 16 percent is the same as 16 over 100, or, 16/100, 100 being the total with an = sign with X over 550, or, X/550. you can multiply 16 by 500 and divide by 100 to get $88. Or you could do it my way, (prefered way). take the $550, divide it by 100, then multiply by 16 and get $88. either way you do this, you take away the $88 from $550 and get the sale price of [Drumroll please...]

SA=2pir^2+2hpir=2pir(r+h)
h=2r=2(2x+3)=4x+6
SA=2pi(2x+3)(2x+3+4x+6)
SA=(4x+6)(pi)(6x+9)
SA=24πx²+27πx+54π
The correct answer is D you get it right;)
Punchline Algebra is carefully sequenced book to help student understand problems which otherwise take a lot of time and effort to understand. An example is that "What can we say about a monster with five legs", and the answer could be <span>"We can say about a monster with five legs that the monster have a pant or trouser that fits him like a glove."
The punchline in this is that pants fit the monster like a glove, and this highlight the figure "five" for a student in an easy fun way.
