Question

Please help me its multiple choice

Answer 1

A) $11.75


—


She bought three water pumps for 26.25

3w = 26.25

w = 8.75

Therefore, one water pump is $8.75

They bought another water pump and carbon filter for $20.50.

w + c = 20.50

Substitute w for what we solved earlier.

8.75 + c = 20.50

Subtract 8.75 on both sides.

C = $11.75

Answer 2

`\huge\boxed{\sf Price\ of\ carbon\ filter = \$11.75}`

Explanation:

Given that,

3 water pumps = $26.25

Using unitary method

• Divide both sides by 3

3/3 water pumps = $26.25/3

1 water pump = $8.75

From the question,

The price of 1 water pump and one carbon filter equal $20.50.

So,

Price of carbon filter = $20.50 - Price of 1 water pump

Price of carbon filter = $20.50 - $8.75

Price of carbon filter = $11.75

`\rule[225]{225}{2}`
