Rebecca sold 11 more magazines subscriptions than chad. laura sold 4 more than rebecca. laura sold 45 magazine subscriptions. how many magazines subscriptions did chad sell

Chad sold 30 magazine subscriptions.

Solution:

Given, Rebecca sold 11 more magazines subscriptions than chad.  

Let the number of magazines sold by chad be "n", then number of magazine sold by Rebecca will be "n + 11"

Given that Laura sold 4 more than Rebecca.  

Then, number of magazines sold by Laura will be 4 + n + 11 ⇒ n + 15

Total magazine sold by Laura = 45

Total magazine sold by Chad = ?

Total magazine sold by Laura = n + 15 = 45  

n = 45 – 15 = 30

Since "n" indicates number of magazine sold by Chad. Thus n = 30 means that Chad sold 30 magazine

step-by-step explanation: got this question

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
