It would be: 567/18 = 31.5

Marcy will need 32 shelves to fit all the earmuffs.

32*18=576.

This means that one of the shelves will not be full, but Marcy will still have to use 32 shelves.

Ipatiy [6.2K]

Answer:

14 correct and 11 wrong

Step-by-step explanation:

If you got a 56% , we need to change this to decimal form 56% = .56

This is the percent you got right

.56* 25 = 14

You got 14 questions right

To determine the number of questions you got wrong, take the total number of questions minus the number you got right.

25-14 =11

You got 11 wrong
