Ok, so on the number of snacks side of the table i know it’s adding three to each number but on the side of the table where it says “total cost” i’m confused because armani says that the constant of proportionality is 1.50,but when i add that to $3.00 it equals 4.5,which is not the following number and when i multiply it’s still not the following number “7.50” but i’m confused as to why angelica says it’s non-proportional. i know it’s non-proportional, but i don’t understand why she says “because it doesn’t include the point (0,0)” when in my perspective, that doesn’t matter. ! ♥️

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.

actually what is a question i don't understand
