7 0

Answer:

0.4

Step-by-step explanation:

15 = 5p - 13

-13 = 5p -13

----------------  ( subtract 13 on both sides )

 <u> 2 = 5p</u>

  5 = 5p

----------------  ( divide 2 by 5 )

  p = 0.4

( p equals 0.4 )

A dozen eggs cosy $1.32 at the grocery store .how much profit would a restaurant make if the sold 1 scramble egg for 99 cent
tatuchka [14]
What we know: A dozen costs 1.32; there are 12 in a dozen.
What we need to know: How much a restaurant makes selling 1 egg at 0.99.
First, find the value of one egg; you can do that by dividing the total cost (1.32) by the amount (12):
1.32 / 12 = 0.11    <--    The cost per egg is 11 cents. To find the profit of the restaurant, just subtract the cost from the price they sell it for:
0.99 - 0.11 = 0.88    <--    The profit the restaurant makes per egg is 88 cents.

Hope this helps.
