price - (1/4)×price = price×(1 - 1/4) = (3/4)×price
... = (3/4)×5.90 = 4.425 ≈ 4.43 . . . . . sale price
_____
The sale price could be 4.42 if the discount is rounded up, rather than the price being rounded up. If you first compute the discount as (1/4)×5.90 = 1.475 ≈ 1.48, then the half-penny goes to the customer, not the shop-keeper.
Answer:
2+3=5
Step-by-step explanation:
100x + 300 = 500
100x = 500 - 300
100× = 200
100x/100 = 200/100
therefore ^x = 2
x + 3 = 5
2 + 3 = 5
Answer: 7 Answers Incorrect
Step-by-step explanation:
86% may be written as (86/100) or as 0.86.
Since "it's a ratio (sic.) problem," then:
86/100 = correct/50
correct = (86/100)*50 (multiply both sides by 50)
correct = 43
And, 50-43 = 7 incorrect
