Sally can paint a house in 4 hours; Which means in 1 hour she can paint 1/4th of the house.

John can paint the same house in 6 hours. Which means in 1 hour she can paint 1/6th of the house.

Together in 1 hour they can paint: - 1/4 + 1/6 = 5/12th of the house.

Total Hours for painting the house together will be 12/5 = 2.4 Hours.

So the answer is 2 hours and 24 minutes

klemol [59]

Answer:

Number of drink = 5

Number of pretzel = 9

Step-by-step explanation:

Given:

Cost of each drink = $4

Cost of each pretzel = $5

Total money = 65

Total number of drink and pretzel = 14

Find:

Number of drink and pretzel

Computation:

Number of drink = x

Number of pretzel = 14 - x

So,

x(4) + (14-x)5 = 65

4x + 70 - 5x = 65

x = 5

Number of drink = 5

Number of pretzel = 14 - x

Number of pretzel = 14 - 5 = 9

A landscaper receives a discount on each plant purchased. The original price of each plant is x dollars. The landscaper purchase
prisoha [69]

Answer:

$4

Step-by-step explanation:

Discount is a form of consideration in price or amount given to a customer on a sale of goods. It can be deduced from the question that;

The original price of each plant = $x

Number of plants purchased = 20

Price of the number of plants purchased without discount = $20x

Amount paid for the 20 plants with discount = $(20x - 80)

Thus,

The discount on the 20 plants = $80

Discount on each plant = \frac{total discount on plants}{number of plants purchased}

                                       = \frac{80}{20}

                                       = $4

Discount on each plant = $4

Therefore, each plant was discounted by $4.
