a supermarket sells 2 kg and 4 kg of sugar a shipment of 1100 bags of sugar has a total mass of 2900 kg. How many 2 kg bags and
Vaselesa [24]

There are 750 (2 kg) bags and 350 (4 kg) bags in the shipment​

Step-by-step explanation:

The given is:

  • A supermarket sells 2 kg and 4 kg of sugar a shipment of 1100 bags of sugar
  • The total mass of the sugar is 2900 kg

We need to find how many 2 kg bags and 4 kg bags are in the shipment

Assume that x represents the number of 2 kg bags and y represents the number of 4 kg bags

∵ x is the number of 2 kg bags

∵ y is the number of 4 kg bags

∵ The total number of bags are 1100

- Add x and y, then equate the sum by 1100

∴ x + y = 1100 ⇒ (1)

∵ The total mass of sugar is 2900 kg

- Multiply x by 2 and y by 4 to find the mass of the bags, then

  add the two product and equate them by 2900

∴ 2x + 4y = 2900 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -2 to eliminate x

∴ -2x - 2y = -2200 ⇒ (3)

- Add equations (2) and (3)

∴ 2y = 700

- Divide both sides by 2

∴ y = 350

- Substitute the value of y in equation (1) to find x

∵ x + 350 = 1100

- Subtract 350 from both sides

∴ x = 750

There are 750 (2 kg) bags and 350 (4 kg) bags in the shipment​

Eli Moran is an accountant at J & R Tax Prep, and during tax season he works overtime to meet the demand. He is paid $32 per
Sati [7]

Answer :

The value of number of hours overtime per week will he needed to achieve his earning goal = 5 hours

Step-by-step explanation:

Payment for first 40 hours = $ 32 per hour

Payment over 40 hours = $ 48 per hour

Eli’s goal is to earn = $ 1520 per week ------- (1)

Total payment for first 40 hours = 32 × 40 = $ 1280 ------ (2)

Suppose person worked x_{} hours in overtime, then

The total payment for x_{} hours = 48 × x_{}  = $ 48x_{} ------------ (3)

Total earnings of the person in a week ⇒ $ 1280 +  $ 48x_{} = $ 1520

⇒ 1280 + 48x_{} = 1520

⇒ 48x_{} = 1520 - 1280

⇒ 48x_{} = 240

⇒ x_{} = 5 hours

This is the value of number of hours overtime per week will he needed to achieve his earning goal.
