Okay so we can try to find how much it’d cost per ounce to see which one would give us the best deal
5.90/10= .59 per ounce

6.48/24= .27

therefore, the 24 oz. box would give us the best deal

Cereal A

10 ounces = $5.90

10/10 ounces = $5.90/10 .... divide both sides by 10

1 ounce = $0.59

1 ounce = 59 cents

----------

Cereal B

24 ounces = $6.48

24/24 ounces = $6.48/24  .... divide both sides by 24

1 ounce = $0.27

1 ounce = 27 cents

We see that Cereal B is the cheaper deal per ounce

---------

<h3>Answer: Cereal B is the better deal</h3>

when the wimen sells 90 oranges Rs160 with dicount of 20%,how many oranges she sell by Rs112 with profit of 20%​
Fynjy0 [20]

She sold 42 oranges with profit 20%

Step-by-step explanation:

The woman sells 90 oranges by RS.160

This price with discount of 20%

We need to find how many oranges she sell by Rs.112 with profit of 20%​

  • Selling price = cost price - discount ⇒ discount case
  • Selling price = cost price + profit ⇒ profit case

Assume that cost price of an orange is x

∵ She sells 90 oranges with Rs.160

- Find the selling price of 1 orange by dividing 160 by 90

∴ The selling price of an orange = \frac{160}{90}=\frac{16}{9}

∵ She sold them with discount 20%

∵ The cost price of an orange is x

- Find the 20% of x

∵ Discount = 20% × x = \frac{20}{100} × x = 0.2x

- To find the selling price subtract 0.2x from x

∴ The selling price = x - 0.2x

∴ The selling price of an orange = 0.8x

- Equate 0.8x by \frac{16}{9} to find x

∵ 0.8x = \frac{16}{9}

- Divide both sides by 0.8

∴ x = \frac{20}{9}

Assume that the number of oranges is y

∵ She sell y oranges for Rs.112 with profit 20%

∵ The cost price of an orange is \frac{20}{9}

- Find 20% of \frac{20}{9}

∵ Profit = 20% × \frac{20}{9} = \frac{20}{100}.\frac{20}{9}=\frac{4}{9}

- Add \frac{4}{9} to cost price to find the selling price

∴ The selling price of an orange = \frac{20}{9} + \frac{4}{9}

∴ The selling price of an orange = \frac{24}{9}

- To find y divide 112 by selling price of an orange

∵ y = 112 ÷ \frac{24}{9}

∴ y = 42

She sold 42 oranges with profit 20%

The length of the base of a triangle is twice its height. If the area of the triangle is 64 square​ kilometers, find the height.
frez [133]
Area of a triangle = base x height / 2
64 = base x height / 2
(multiply 2 on both sides)
128 = base x height 
then if base= 16 and height = 8 then 16 x 8 = 128
thus the base is 16 which is twice the height:8
