Step-by-step explanation:

Let x = Number of one flavor of cakes

y = Number of other flavor of cakes

According to the question

Divide (ii) by 5 , we get

Eliminate (i) from (iii), we get

Put this in (i), we get

Hence, 40 one flavor cakes and 60 other favor of cakes were donated.

you would need to know all the numbers that are on there

step-by-step explanation:

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.
