11. An electronics-store manager knows that he will order up to $7,000 of
merchandise to restock his inventory.
He will order both computers and cell
phones. Each computer costs the store
$200, and each cell phone costs $100.
He can have in inventory a maximum of
45 cell phones and 30 computers. Each
computer is estimated to bring a profit
of $400. Each cell phone is estimated to
bring a profit of $100. How many com-
puters and cell phones should he pur-
chase to maximize profit? How much
money will the manager make if he sells
all the items purchased?

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

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

d 600 because 15*10*2=300

300+300=600
