Mathematics
1 answer:
Schach [20]2 years ago
3 0

Answer: See below

Step-by-step explanation:

A) -x+2y < -4

-x+2y-2y < -4-2y

-x < -4-2y

Multiply both sides by -1 and reverse the inequality:

\left(-x\right)\left(-1\right) > -4\left(-1\right)-2y\left(-1\right)

x > 4+2y

B) 2x+3y > 6

2x+3y-3y > 6-3y

2x > 6-3y

\frac{2x}{2} > \frac{6}{2}-\frac{3y}{2}

x > \frac{6-3y}{2}\\x > 3-\frac{3y}{2}

The Fruitz fruit and vegetable shop is selling grapes at a price which is 10% cheaper than the Happy Fruiterer fruit and vegetab
sdas [7]

Answer:

(a) It costs $55 at Happy Fruiterer

(b) It will cost $49.64

(c) It is cheaper at Happy Fruiterer the second week

Step-by-step explanation:

Since Fruitz shop sells as 10% less than Happy Fruiterer at $50

10% more of $50 = 50 × 10/100 + 50

= $5 + $50 = $55

(a) n Kg of grapes will cost $55 at Happy Fruiterer

(b) if Happy Fruits discounts $55 by 5%, we will have

55 × 5/100 = 2.75

that is $55 - $2.75 = $52.25

If it is discounted further at 5% more the following week, we will have

$52.25 × 5/100 = $2.6125

≈ $2.61

Then the new price for the 2nd week is $52.25 - $2.61

= $49.64

(c) at the second wee of discounting, Fruitz shop still sells at $50 will Happy Fruiterer now see at $49.64. Therefore, it is cheaper at Happy Fruiterer
