Twelve men take 6 hours to finish a piece of work.
In 1 hour, the 12 men will finish 1/6 of the work
( 1 job ) / ( 6 hrs ) = ( 1/6 of a job ) / ( 1 hr )
-----------------------------------------
That means there is of the job
left to do.
-------------------
If 12 men take 6 hours to finish a piece of work,
1 man will take 12 times as long, to finish the work, so
( 1 job ) / ( 6*12 = 72 hrs ) = rate of working for 1 man, or
-------------------
After 1 hour, there are a total of men working
20 men will work 20 times as fast as 1 man on the
of a job that remains, so
Let = hours for the 20 men to finish the job
Answer: they have 68 servings of ice cream left for the party
Step-by-step explanation:
The Smiths purchased 6 containers of ice cream for a party. Each container holds 9 cups of ice cream. This means that the total number of cups of ice cream that they have is
6 × 9 = 54 cups
Before the party, their sons ate 3 cups of ice cream altogether. This means that the number of cups of ice cream that they have left is
54 - 3 = 51 cups
One serving is 3/4 cup of ice cream. This means that the number of serving that they have left is
51/0.75 = 68
Answer:
$225.54 (hope it help)
Step-by-step explanation:
for 2nd week
$150 for the first week and a raise of 6% each week
which means 150+6%
6% of 150 is 9 (150x0.06)
150+9=159
and it repeats
for 3rd week
6% of 159 is 9.54 (159x0.06)
159+9.54=168.54
for 4th week
6% of 168.54 is 10.1124 (168.54x0.06)
168.54+10.1124=178.652
for 5th week
6% of 178.652 is 10.71912 (178.652x0.06)
178.652+10.71912=189.37112
an easier to do it is to just do 178.652 + 6% on your calculater
and I'll skip all the way to the 8th since you know the formula
212.777390432+6%=225.544033858
225.544033858≈225.54
