D. 30%

30%

Step-by-step explanation: Reading through the problem we have 24 is, that's 24 equals, what percent means x/100, of 80, means times 80.

Notice that I put x/100 for what percent since percent means over 100.

Cross-canceling the 80 and 100 to 4 and 5, we have 24 = 4x/5.

Multiplying both sides by 5 to get rid of the fraction, we have 120 = 4x.

Now dividing both sides by 4, we find that 30 = x.

Remember the problem is asking for what percent so we should write our answer as 30% to answer the question.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
