Serga [27]
If its meaning making a profit after the $300 then:
540+300=840
840/24= 33.60
They would charge $33.60 per necklace.

If you were meaning a profit of $540 total then:
540/24=22.5
They would charge $22.50 per necklace.

Tyrone has 8/9 of a foot of string. He needs to cut pieces of string that are 1/4 of a foot long. How many whole 1/4 foot pieces
Gekata [30.6K]

9514 1404 393

Answer:

  3

Step-by-step explanation:

You can use your number sense to realize that 8/9 is between 3/4 and 1, so Tyrone can only get 3 whole pieces from his string.

__

If you like, you can do the division ...

  (8/9)/(1/4) = (8/9)(4/1) = 32/9 = 3 5/9 . . . . . 3 whole pieces

Or, you can compare decimal values.

  1 piece = 0.25 ft

  2 pieces = 0.50 ft

  3 pieces = 0.75 ft

  4 pieces = 1.00 ft

String length = 0.888.... ft (more than 3; less than 4 pieces)
