If you wrote all of the numbers from 300 to 400 on a piece of paper, how many times would you have written the number 3

answer: #1 ads up by 8 and i don't know #2

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
