A washing machine sells for $201 after being discounted by 40 percent. What was the original price of the washing machine?
olga_2 [115]

Step-by-step explanation:

Let original price be x

Price after 40% discount is $201

Therefore

x × 40% = $201

x = 201 ÷ (40/100)

x = 502.5

Therefore, the original price is $502.5

Hope it helps :)

Math help what is the answer will give brainliest.
artcher [175]
The two equations are
x + y = 7
and
4x + 2.5y = 22
the first equation can be solved for x to be
x = 7 - y
next you can substitute x in the second equation
4(7 - y) + 2.5y = 22
Distribute 4 to everything in the parentheses
28 - 4y + 2.5y = 22
combine like terms:
28 - 1.5y = 22
subtract 28 from both sides of the equation
- 1.5y =  - 6
divide both sides by -1.5
y =  4
plug this in to the original equation of x+y=7
x + 4 = 7
subtract 4 from both sides.
x = 3
