The laundry has been sorted into dark clothes and light clothes. the number of dark clothes is three more than twice the number of light clothes. the laundry is 60% dark clothes. choose the equation that best represents this scenario.

We can represent this question as a system of equations

Let

x = number of dark clothes

y = number of light clothes

L = total number of clothes

The number of dark clothes is three more than twice the number of light clothes

x = 2*(y) + 3

The laundry is 60% dark clothes.

x  = 0.6*(L)

x=3+2y and 2x=3y

Step-by-step explanation:

Let the number of dark clothes be x

and that of light clothes be y

It is given in the condition that

x= 3 more than twice of y

x=3+2y ------------------------------ ( I )

Also it is given that 60% clothes are dark

Hence

doing cross multiplication

2x=3y ----------------------------------- (II)

Hence equation (I) and (II) represent the two conditions given in the problem.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
