Step-by-step explanation:

GIVEN :  Mr. carter and Ms. torres need two buses to drive their classes to the amusement park. each class needs money to rent the bus and 20 to tip the driver. the two classes together raised $240.

To Find : . how much money can they spend on each bus rental?

Solution :

Let the rental of each bus be b

And each bus driver was given 20 as tip

so, total cost for 1 bus = b+20

Cost for two buses = 2(b+20)

since we are given the two classes together raised $240

⇒2(b+20)=240

Hence Option C is correct

c. 2(b+20)=240

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
