For a given recipe, 8 cups of flour are mixed with 12 cups of sugar. How many cups of
sugar should be used if 22 cups of flour are used?
Assuming a constant ratio, fill out the table of equivalent ratios until you have found
the value of x.
Flour
Sugar
12
22

, There should be 33 cups of sugar if 22 cups of flour are used.

Step-by-step explanation:

I solved it using the proportion method.

For the ratios in between, multiply both numbers in the ratio by one, two, three, four, etc, until the flour number becomes 22.  

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.
