Your party is expected to have 20 people including you. Each person gets one fork and one spoon. There are 6 spoons in
one package and 8 forks in one package.
a.
What is the least number of packages of spoons you
need to buy?
What is the least number of packages of forks you need
to buy?

4 packages of spoons and 4 packages of forks

Step-by-step explanation:

spoons: divide the number of people (20) by the number of spoons in one package (6) and you get a little under 4 but you need to round up since you can't buy part of a pack

forks : divide the number of people (20) by the number of forks in one package (8) and you get a little under 4 but you need to round up since you can't buy part of a pack

answer:

sometimes

*i think

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
