Situation, Stella wants to build up her emergency fund to $10,000. She has $2,000 now and plans on saving 5320 every month. To model
she creates this equation, where x represents the number of months and y represents the total amount in her emergency fund:
y = 2,000 + 320x
Determine the missing steps and justifications in her work.
y - 2,000 = 2,000 + 320x - 2,000
division property of equality
y - 2,000
320 SX
10,000 - 2,000
320 = 25 = x
8,000 - 200
320 = 24 = x
y - 320
2,000 = x
y - 2,000 = 2,000 - 320x - 2,000
multiplication property of equality
Steps
Justification
y = 2,000+ 320x
given
subtraction property of equality
y - 2,000 = 320x
simplification
y-2,000

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
