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

64/2= 32
Answer:
x<6 this is the answer because the circle is hallow (not including) and going left (less than)
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange x + 5y = 10 into this form
Subtract x from both sides
5y = - x + 10 ( divide all terms by 5 )
y = -
x +2 ← in slope- intercept form
with slope m = - 
• Parallel lines have equal slopes, hence
y = -
x + c ← is the partial equation of the parallel line
To find c substitute (1, 3) into the partial equation
3 = -
+ c ⇒ c = 
y = -
x +
← equation of parallel line
