Please Help :Last Year three 6th grade students , Aliya, Crystal, And Shamika, we’re selling balloons at the schools Winter Dance to collect $305 for a class trip to the Zoo. Aliya sold 2 more balloons than Crystal, And Shamika sold twice as much balloons as Crystal. Let “C” represent the total number of balloons Crystal Sold.


Total Ballons Sold : 122


F) Which number in the following set represents the amount of balloons sold by Crystal?


{ 30, 31, 116, 118 }


Thanks

It would take a work crew of 4 people approximately 5 days and 18 hours to complete the same job if each person in both crews works at the same rate as each other.

To solve this problem, we can start by calculating the total work done by the original work crew of 3 people in terms of "work-weeks." We know that they require 3 weeks and 2 days to complete the job.

1 week = 7 days

So, 3 weeks and 2 days can be converted to days as follows:

3 weeks + 2 days = 3 weeks + (2/7) weeks

≈ 3 weeks + 0.2857 weeks

≈ 3.2857 weeks

Now, we know that the original work crew of 3 people completes the job in 3.2857 work-weeks.

Next, we can calculate the amount of work done by each person of the original crew per work-week:

Work done by 1 person in 1 week = 1/3 of the total work (as there are 3 people)

Work done by 1 person in 1 work-week ≈ 1/3.2857

Now, we want to find out how much work a single person of the new work crew of 4 people can do in 1 work-week. Since each person in both crews works at the same rate, the work done per person per week will be the same.

Work done by 1 person in 1 work-week ≈ 1/3.2857 ≈ 0.3043

Now, we know that a single person from the new crew can complete approximately 0.3043 of the total job in one work-week.

Finally, we want to find out how long it will take for the new work crew of 4 people to complete the entire job. Let's denote the time in weeks as "x."

Total work done by the new crew of 4 people = 4 people * x weeks * 0.3043 work done per person in 1 week

Total work done by the new crew of 4 people = 1 job (as they will complete the entire job)

So, we have the equation:

4x * 0.3043 = 1

Now, solve for "x":

x ≈ 1 / (4 * 0.3043)

x ≈ 0.8225

Therefore, it would take a work crew of 4 people approximately 0.8225 weeks to do the same job. To convert this into days:

0.8225 weeks * 7 days/week ≈ 5.7575 days

So, it would take a work crew of 4 people approximately 5 days and 18 hours to complete the same job if each person in both crews works at the same rate as each other.
