17. A restaurant has 30 seating options for its guests, including both tables and booths. Each
booth seats 4 guests and each table seats 8
guests. The maximum number of guests that can
be seated at any time is 128. Which of the
following systems models this information and
would be used to find the numbers of tables and
booths in the restaurant?
A) 4t + 8b = 30; t + b = 128
B) t+b = 30; 8t + 4b = 128
C) t+ b = 30; 4t + 8b = 128
D) 4t + 8b = 128; 4t + 8b = 30

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

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
