The Freeman Family is barbecuThe Freeman Family is barbecuing veggie burgers corn on the cob and mushroom caps in the local park if 3/8 of the items barbecued or veggie burgers and 1/3 of the item barbecue or call in the car with friction or barbecue items are mushroom caps

7 by 24 of barbecue items would be considered as mushroom caps

Step-by-step explanation:

The fraction of barbecue items considered as mushroom caps is given below:

Let us assume the number of barbecue items be x

So,

x = Veggies burgers of barbecue + corn cobs of barbecue + mushroom caps of barbecue

Now

Veggies burgers of barbecue = (3 ÷ 8)x

corn cobs of barbecue = (1 ÷ 3)x

And, we assume the mushroom caps of barbecue be y

Now the equation would be  

x = (3 ÷ 8)x + (1 ÷ 3)x + y

Now multiplied by 24 to both the sides  

24x = 9x + 8x + 24y

24x = 17x + 24y

24y = 24x - 17x

24y = 7x

y = (7 ÷ 24)x

This means that 7 by 24 of barbecue items would be considered as mushroom caps

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.
