Abasketball clinic charges $200 per player for a group of 25 players. what a group brings 35 players, the rate is reduced to $150 per player. what is the decrease in the cost per player (rate of change)?

Decrease in the cost per player will be 25 .

Explanation:

Since we have given that

Number of player = 25

Amount charges by basket ball clinic = $ 200

Total amount earned by basket ball clinic = 25 ×200=$ 5000

Number of player = 35

Amount reduced to = $ 150

Now, total amount earned by basket ball clinic = 35× 150= $5250

Now, we will calculate the slope

As we know the formula of slope which is given by

So, Decrease in the cost per player will be 25 .

Amount taken by basketball clinic per player if the group consists of 25 players=$200

Total amount charged=$200 × 25= $5,000

Amount taken by basketball clinic per player if the group consists of 35 players=$150

Total amount charged=$150×35=$5250

Rate of change =[( Total Amount taken by basketball clinic per player if the group consists of 35 players) - (Total Amount taken by basketball clinic per player if the group consists of 25 players)]   /     (35 -25)

                    =

   =250/10

   =25

Rate of change i.e decrease in cost per player =$25

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

i believe the answer is c.
