Universal Pet house sells vinyl doghouse and treated lumber doghouses. It takes the company 5 hours to build a vinyl doghouses a
LuckyWell [14K]

Answer:

The system of equations is :

Equation 1- 5x+2y=50

Equation 2- x+2y=30

Number of vinyl doghouse = 5

Number of treated lumber doghouse =12.5

Step-by-step explanation:

Let x be the number of vinyl doghouses

y be the number of treated lumber doghouses

→If it takes the company 5 hours to build a vinyl doghouses and 2 hours to build a treated lumber doghouse. The company dedicates 50 hours every week towards assembling and painting doghouses.

Equation 1- 5x+2y=50

→It takes an additional hour to paint each vinyl doghouse and an additional 2 hours to assemble each treated lumber doghouse. The company dedicates 30 hours every week towards assembling and paining dog houses.

Equation 2- x+2y=30

→When we solve these equation we get the number of  vinyl doghouse and treated lumber doghouse.

Subtract equation 2 from equation 1

5x+2y-x-2y=50-30

4x=20

x=\frac{20}{4}

x=5

Put value of x in equation 2

x+2y=30

5+2y=30

2y=25

y=\frac{25}{2}

y=12.5

Therefore, number of vinyl doghouse = 5, number of treated lumber doghouse =12.5

How to convert 8.5 hours to hours and minutes
ExtremeBDS [4]
A. 4.25 hrs.....4 25/100 reduces to 4 1/4.......1/4(60) = 60/4 = 15 minutes
    so 4.25 hrs = 4 hrs and 15 minutes

b. 8.5 hrs.....8 5/10 reduces to 8 1/2.....1/2(60) = 60/2 = 30 minutes
    so 8.5 hrs = 8 hrs and 30 minutes

c. 6.2 hrs.....6 2/10 reduces to 6 1/5.....1/5(60) = 60/5 = 12 minutes
    so 6.2 hrs = 6 hrs and 12 minutes

d. 10.8 hrs.....10 8/10 reduces to 10 4/5.....4/5(60) = 240/5 = 48 minutes
    so 10.8 hrs = 10 hrs and 48 minutes
