Answer:
The discount% is 15%
Step-by-step explanation:
Given : The price of a sweater was slashed from Rs 960 to Rs 816 by a shopkeeper in the winter season.
To find : The rate of discount given by him?
Solution :
According to question,
The market price of the sweater is Rs.960
The selling price of the sweater is Rs.816
The discount on the sweater is given bY
Discount % is given by
Therefore, The discount% is 15%.
5(2x - 8) + 15 = -15
-15 -15 subtract 15 from each side
5(2x - 8) = -30
÷5 ÷5 divide both sides by 5
2x - 8 = -6
+8 +8 add 8 to each side
2x=2
÷2 ÷2 divide both sides by 3
x = 1
Checking:
5(2(1)-8) + 15 = -15
5(-6) + 15 = -15
-30 + 15 = -15
-15 = -15 Correct! x=1
3x - 12 = -15
Add 12 on both sides.
-12 + 12 = 0
-15 + 12 = -3
The equation is now 3x = -3.
Divide both sides by 3 to isolate the variable.
3x / 3 = x
-3 / 3 = -1
So, x = -1.
