Ji and Layla played a game in which they scored 10 points for a correct answer and lost 20 points for an incorrect answer. Ji answered 7 questions correctly and 3 questions incorrectly. Layla answered 5 questions correctly and 1 question incorrectly. Who had the higher score? By how many points?

Answers

Answer 1
Answer:

Layla had the higher score by 20 points.

Step-by-step explanation:

Given,

Points for correct answer = 10 points

Points for incorrect answer = 20 points

Loss means subtraction;

Therefore,

Total points of Ji = Correct answers*10 - Incorrect answers*20

Total points of Ji = 7*10 - 3*20

Total points of Ji = 70 - 60

Total points of Ji = 10 points

Total points of Layla = Correct answers*10 - Incorrect answers*20

Total points of Layla = 5*10 - 1*20

Total points of Layla = 50 - 20

Total points of Layla = 30 points

Difference = Points of Layla - Points of Ji

Difference = 30 - 10 = 20 points

Layla had the higher score by 20 points.

A worker at a mill is loading 5 pound bags of flour into boxes to deliver to a local warehouse. Each box holds 16 bags of flour. If the warehouse orders 4 tons of flour how many boxes are needed to fulfill the order ?

Answers

Answer:

100

Step-by-step explanation:

volume of 16 bags of flour: 16 x 5 = 80 pounds

We know that: 1 ton = 2,000 pounds -> 4 tons = 2,000 x 4 = 8,000

So we need: 8,000 : 80 = 100 boxes to fulfill the order
