Tom starts lawn mowing business before he can begin he purchases a new lawnmower each weekend he mows the same number of lawns and earns the same amount of money write and equation to show how much money he's earned any week

B. y = 60x - 150

Step-by-step explanation:

From week 1 to week 2 he earn -30 - (-90) = $60

From week 2 to week 3 he earn 30 - (-30) = $60

This profit is repeated every week, and 60 represent the slope of the line that relates y and x.

Then, the y value for week 0 is -150, in this way:

From week 0 to week 1 he earn -90 - (-150) = $60

the same value as before is satisfied. -150 is the y-intercept of the line (the y value when x = 0). Therefore, the equation is:

y = slope*x + y-intercept = 60x - 150

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
