If 50 oranges cost 25.00, how many oranges can be bought for 15.00

We can buy 30 oranges

Step-by-step explanation:

We can use ratios to solve

50 oranges         x oranges

=

25 dollars             15 dollars

Using cross products

50*15 = 25x

Divide each side by 25

50*15/25 = 25x/25

30 =x

We can buy 30 oranges

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
