In 2014 , 2277 was 110% of 2013.

Number in 2013 = 90% of the year before (2012)

Let the number in 2013 be x. From the first statement,

2277 = 110% of x

2277 = (110/100)x

2277 = 1.10x

x = 2277/1.1 = 2070

Number in 2013 is 2070

Number in 2013 = 90% Number in 2012

2070 = (90/100) * Number in 2012

2070 = 0.90 * Number in 2012

2070 / 0.90    = Number in 2012

2300  = Number in 2012

Number in 2012  =  2300

Timmy is helping his grandpa on his chicken farm. Timmy has to pack 66 eggs into cartons, minimizing the packing cost. He can us
Orlov [11]

The way to distribute the eggs at the lowest cost would be using 5 cartons of 12 eggs and 1 carton of 6 eggs.

Since Timmy is helping his grandpa on his chicken farm, and he has to pack 66 eggs into cartons, minimizing the packing cost, and he can use 12-egg cartons and 6-egg cartons, and two 12-egg cartons cost as much as three 6-egg cartons, to determine how many cartons of each should be used, the following calculation must be performed:

  • 2 x 12 = 3 x 6
  • 24 = 18
  • Thus, assuming as an example that a total of 2 cartons of 12 eggs and 3 cartons of 6 eggs cost $ 3, the value of each carton would be the following:
  • 3/3 = 1
  • 3/2 = 1.5  
  • 66/12 = 5.5
  • 5 x 1.5 + 1 x 1 = X
  • 7.5 + 1 = X
  • 8.5 = X

In this way, the way to distribute the eggs at the lowest cost would be using 5 cartons of 12 eggs and 1 carton of 6 eggs.

Brody worked 8.5 hours at Food Lion this week and made $78.20. Based on the number of hours Brody worked and how much he was pai
Lynna [10]

Answer:

1 hour = $9.2

Step-by-step explanation:

The question says that:

Brody makes $78.20 in 8.5 hours.

So,

8.5 hours = $78.20

We need to find 1 hour pay.

So, divide both sides of the above equation by 8.5

8.5 / 8.5 hours = $78.20 / 8.5

1 hour = $9.2

\rule[225]{225}{2}

Hope this helped!
