Trent needs a total of $320 to buy a new bicycle. He has $35 saved. He earns $15 each week delivering newspapers. How many weeks will Trent have to deliver papers to have enough money to buy the bicycle?

Trend wants to buy a new bicycle which costs 320$.

He has 35$ saved and earns 15$ each week.

After a number of weeks (a), the amount money he has: A = 35 + 15 x a

If Trend has enough money to buy that bicycle, we have the equation:

35 + 15 x a = 320

=> 15 x a = 320 - 35

=> 15 x a = 285

=> After 19 weeks, Trent will have had enough money to buy that bicycle

Hope this helps!

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
