Answer:

The change in the total cost for each book printed is $10

The cost to get started is $1250

Step-by-step explanation:

In the linear equation y = m x + b, where

  • m is the rate of change per unit
  • b is the initial amount (value y at x = 0)

∵ y represents the total cost of publishing a book in dollars

∵ x represents the number of copies of the book printed

∵ y = 1250 + 10 x

- Compare it with the linear equation y = m x + b

∴ m = 10

∴ b = 1250

∵ m = Δy/Δx

- That means m is the change in the total cost per book

∴ The change in the total cost for each book printed is $10

∵ b is value y at x = 0

- That means b is the cost to get started before print any book)

∴ The cost to get started is $1250

Lisa [10]

Answer:

Step-by-step explanation:

Given that there are six different toys and they are to be distributed to three different children.

The restraint here is each child gets atleast one toy.

Let us consider the situation as this.

Since each child has to get atleast one toy no of ways to distribute

any 3 toys to the three children each.  This can be done by selecting 3 toys from 6 in 6C3 ways and distributing in 3! ways

So 3 toys to each one in 6x5x4 =120 ways

Now remaining 3 toys can be given to any child.

Hence remaining 3 toys can be distributed in 3x3x3 =27 ways

Total no of ways

= 120(27)

= 3240
