Answer 3

what is the cost to got started (before any books are printed)?

Answer 4

get*

Answer 5

from what you have wrote above result that you need calcule the value of y for x=0 - yes ?

Answer 6

do you can calcule it so in this way ?

Answer 7

yes

Answer 8

y=
x=

Answer 9

ok this mean that so you will get the right answer to this first question

Answer 10

what mean this y= and x= ???

Answer 11

this whole equation is is just confusing, I have no idea how to solve it. Can you walk me through the steps?

Answer 12

y=1100 +15x so how you have wrote in the text of your exercise y mean the cost of x printed books

- yes ?

Answer 13

yes

Answer 14

so for the start when the printed booke number is zero so just you need substituting the zero in place of x inside this equation of y and make the calcule so will get the started necessary cost

Answer 15

y=1100 +15x

y=1100 +15*0

y = ?

Answer 16

1100?

Answer 17

exactly - so was hard ?

Answer 18

not at all, thanks.

Answer 19
