Answer:

$7.60

Step-by-step explanation:

Use a linear function (again)

let x = peanuts

let y = almonds

3x+4y=27.45

5x+2y=24.05

Multiple 2nd equation by 2

3x+4y=27.45

10x+4y= 48.1

7x=20.65

x=2.95

Plug in x into either equation

10x+4y= 48.1

29.5+4y=48.1

4y=18.6

y=4.65

4.65+2.95=7.60

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 :)
