A. the rate of change is 100 because it went up 100 each year. I know this because I subtracted 350 from 750 and got 400 and divided it by the number of remaining year.

B. x+350=750 
Hope this helps!!

Check the picture below.

now, to get how much is the area of the tiled section, we simply get the area of the whole pool, 53x26, which includes the tiles, and then subtract the area without the tile, the rectangle in the middle, and what's leftover, is the area of the tiled area.

$\bf 53-4\frac{1}{2}-4\frac{1}{2}\implies 53-9\implies \boxed{42}
\\\\\\
26-4\frac{1}{2}-4\frac{1}{2}\implies 26-9\implies \boxed{17}
\\\\\\
\textit{so the area of the rectangle in the middle is}\implies 42\cdot 17\implies 714
\\\\\\
\textit{and the area of the whole pool is}\implies 53\cdot 26\implies 1378$

$\bf \stackrel{\textit{area of the whole pool}}{1378}~~-~~\stackrel{\textit{area of the middle rectangle}}{714}\implies \stackrel{\textit{area of the tiles}}{664}\\\\
-------------------------------\\\\
\textit{we know that is }\$5\frac{1}{2}\textit{ for a foot of tile, then}\stackrel{\textit{price of the tiles}}{664\cdot 5\frac{1}{2}}\implies 3652$

52 is what percent of 260

chubhunter [2.5K]

if we take 260 to be the 100%, what is 52 off of it as a percentage?

$\bf \begin{array}{ccll} amount&\$\\ \cline{1-2} 260&100\\ 52&x \end{array}\implies \cfrac{260}{52}=\cfrac{100}{x}\implies 5=\cfrac{100}{x} \\\\\\ 5x=100\implies x = \cfrac{100}{5}\implies x=20$
