B) $164
Step-by-step explanation:
A) Marked Price (Original Price)
= 
=
=87.5
B) Marked Price (Original Price)
=
=
=164
To answer this problem you have to use a ratio, if it begins with 8:500, multiply 40 or 20,000/500 on both sides to get 320:20,000
1. (x−1)(5x+8)−2x+5
=(x)(5x)+(x)(8)+(−1)(5x)+(−1)(8)+−2x+5
=5x2+8x+−5x+−8+−2x+5
Combine Like Terms:
=5x2+8x+−5x+−8+−2x+5
=(5x2)+(8x+−5x+−2x)+(−8+5)
=5x2 + x + −3
2. (−2+5)(3x+9)
=9x+27
3. 2x+5−8x+12
=2x+5+−8x+12
Combine Like Terms:
=2x+5+−8x+12
=(2x+−8x)+(5+12)
=−6x+17
4. (−x+3)(−5x−2)
=(−x+3)(−5x+−2)
=(−x)(−5x)+(−x)(−2)+(3)(−5x)+(3)(−2)
=5x2+2x−15x−6
=5x2 − 13x − 6
Rectangle on the left = 3 × 4 = 12
Rectangle in the middle = 3 × 2 = 6
Rectangle on the right = 4 × 3 = 12
Add:
12 + 6 + 12 = 30
Answer = 30
