Nady [450]

Answer:

y=3x

Step-by-step explanation:

If y is the total distance from the shore and it increases by 3 miles every hour, then by plugging in the amount of hours that have passed into x we will find the distance they have traveled. For example, if they have been out for 5 hours then you would do y=3(5) which would be 15 miles from the shore.

8_murik_8 [283]

Answer:

-43 necklaces.

-total expenses=Sales=$473

Step-by-step explanation:

The breakeven point is the point where the sales revenue equals the expenditure.

-The fixed expenses is $172

-Let x be the number of necklaces sold, the breakeven point is expressed as:

Sales= Expenses\\\\11x=7x+172\\\\4x=172\\\\x=43

Hence, Shelby has to sell 43 necklaces to breakeven.

#The expenses at the breakeven point is:

E=7x+172\\\\=7\times43+172\\\\=473

Hence, expenses at breakevent point is $473

#Sales is equal to expenses at this point, hence, sales of $473
