The first one would be 1 dash after the last one. The second one would be in the middle of the 3rd and 4th dash, the 3rd would b at 2. The fourth would b slightly after the 1st dash after 3. And the last would be in the middle of the 1st dash after 2.5 and the 2nd
X-0.20x=5.56
Solve for x
So the original price is
X=6.95
-2/3x +1/3 +x = 2/5
⇒ 1/3x + 1/3 = 2/5
⇒ 1/3x = 2/5 -1/3
⇒ x/3 = 1/15
⇒ 15x = 3
⇒ x = 3/15
⇒ x = 1/5
