The example of real life situations is: The cost of 30 green apples is €60
Rox wants to buy only 5 apples, how much will they cost her?

Cost of 30 green apples is €60.
Cost of 1 green apple = €60/30 = €2
(Using the concept of division of rational numbers)
Now, cost for 5 green apples =5 * €2 = €10

A baseball stadium holds 15,002 seats. The lower level has 50 fewer than three times as many seats as the upper
Elanso [62]

Answer:

B) The equation <em>x </em><em>+ </em><em> (2 x + 40)  + (3 x - 50)   =  15,002 </em> represents this scenario suitable.

Step-by-step explanation:

Let x represent the number of  upper-level seats.

Total seats in stadium = 15,002

Now, seats in the lower level =  3 ( Seats in upper level ) - 50

= 3x - 50

or, the total seats in the lower level = (3 x - 50)

Also,  seats in the middle level =  2 ( Seats in upper level ) + 40

= 2x + 40

or, the total seats in the middle level = (2 x + 40)

Now, according to question

Upper Level seats + Middle level seats + Lower level  = Total seats

⇒ (x) +  (2 x + 40)  + (3 x - 50)   =  15,002 seats

Hence, the equation <em>x </em><em>+ </em><em> (2 x + 40)  + (3 x - 50)   =  15,002 </em> represents this scenario suitable.

PLEASE HELP!! I’LL MAKE YOU BRAINIEST!
Leokris [45]

Answer:

1. Markup: $2.70, Retail: $20.70

2. Markup: $9.45, Retail: $31.95

3. Markup: $25.31, Retail: $59.00

4. Markup: $24.75, Retail: $99.74

5. Markup: $48.60, Retail: $97.20

6. Markup: $231.25, Retail: $416.25

Step-by-step explanation:

To get the markup price of an item, multiply it by the markup percentage as a decimal. To get the decimal of a percentage, divide the number by 100. For example, 15% would be 0.15. And then to find how much the item has been marked up by, multiply the current price by the decimal.

$18 * 0.15 = $2.70

So $2.70 is the markup. To find the retail price, you need to add the markup price to the current price given.

$18 + $2.70 = $20.70

So your retail price is $20.70. Repeat these steps for each question to get the answers above.

Hope this helps.
