Answer:
Marked Price =MP=550 Marked Price =MP=550
Selling Price=SP=550-10%=550-55=495Selling Price=SP=550-10%=550-55=495
The profit earned is , SP−Profit=CP(CostPrice)The profit earned is , SP−Profit=CP(CostPrice)
CP=495−75=420CP=495−75=420
The difference of MP and CP is 550−420=130The difference of MP and CP is 550−420=130
The percentage of difference w.r.t CP is The percentage of difference w.r.t CP is
130420×100=30.95%
Step-by-step explanation:
plz make me as a brainliest
We have an equation: ?/100= 25/752
Cross multiply:
752*?= 25*100
⇒ ?= 25*100/752= 3.32
3.32% of 752 is 25~
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
y-x> 0 -----> inequality A
y> x
The solution of the inequality A is the shaded area above the dashed line y=x
x+1<0 ----> inequality B
x < -1
The solution of the inequality B is the shaded area at the left of the dashed line x=-1 (open circle)
therefore
The solution of the system of inequalities in the attached figure
