Answer:
200
Step-by-step explanation:
Let market price = y
According to question
160+20% of y=y
160+20/100y=y
160=y-20/100y
160=100/100y-20/100y
160=80/100y
160×100/80=y
y=200
Answer: 7 inches
Step-by-step explanation:
If x is the first piece, and the second piece is twice as long, then the second piece is 2x.
If the third piece is three times as long as the first piece, x, then the third piece is 3x.
The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.
42 = x + 2x + 3x
42 = 6x
42 = 6x
7 = x
The first piece is 7 inches long.
