Answer:
Step-by-step explanation:
Original price that she paid for the dish washer is £240. She wants to sell it and make a profit of 25%. It means that price at which she would make a profit of 25% is
240 + 25/100 × 240 = 240 + 60 = 300
To determine the price tag of 40% discount and that would still ensure that she makes £300,
Let x represent the price tag in £. It means that a discount of 40% on £x would be 300. A discount of 40% on £x is expressed as
x - (40/100 × x) = x - 0.4x = 0.6x
So 0.6x = 300
x = 300/0.6 = 500
So the price tag will be £500
The solution of -2(3x+9)=24 is x= -7
The correct answer is 3/4

+ (n - 1 )d, hence
= 13 + (5 × 4 ) = 13 + 20 = 33
