1. 428 pages: <em>There are a total of 428 pages</em> that you can flip to.
2. 1/428: Page 45 is <em>only one page out of the total sample space</em>.
3. 1/2: Since the last page is 428, there is an even number of pages. That means that there are<em> 214 page numbers that are even</em>. <em>214/428 = 1/2</em>.
y = kx is the formula for direct variation
8 = k*20
divide by 20
8/20 =k
divide by 4
2/5 =k
y = 2/5 x
formula: y = 2/5x
b) y=2/5x
y = 2/5 *7
y = 14/5
or as a mixed number 2 4/5
