Answer:
12 inches
Step-by-step explanation:
To solve you have to set up a ratio. Because both buildings are being shrunk the exact same amount, you just have to account for the size difference from the miniature and real life. The ratio is 21:3 and 84:x. To find x you just have to cross multiply and solve.
The equation comes out to be 252 = 21x
Divide both sides by 21 to get x.
252/21 = 12
The size of the 84 foot building as a model is 12 inches.
1st step: find what is 9.8% of $96,812
9.8% = .098
(.098)(96,812)
= 9,487.576
2nd step: Add 96,812 and the result of the last step.
96,812 + 9,487.576
= 106,299.576
This rounded to the nearest dollar then equals 106,300 dollars
