So you know the merchant made a 15% profit on the pen, so she bought it for a cheaper price. To find the cost of the pen before you have to take the price now, $6.90 and times it by 85%. You do 85% because you subtract the 15% she saved from 100% and you get 85%. So 6.90x.85= 5.865 which rounds to $5.87
3 is in the thousands
so the answer is 3000
To write this as an improper fraction you would multiply 9 by 1 then add your product to the numerator.
9x1=9
9+8=17
17/9

Answer:
y = 1
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 25 when x = , then
25 = = 5k ( divide both sides by 5 )
5 = k
y = ← equation of variation
When x = 5, then
y = = 1
