8 customers entered a store over the course of 16 minutes. At what rate were the customers entering the store in minutes per cus
lilavasa [31]

Answer:

<h3>2min/customer</h3>

Step-by-step explanation:

If 8 customers entered a store over the course of 16 minutes, then;

8 customers = 16 minutes.

The rate at which the customers are entering is expressed as;

Rate = Time (in minutes)/amount of customers;

Given

Time = 16 minutes

Amount of customers = 8 customers

Rate = 16min/8customers

Rate = 2min/customer

Hence the rate at which the customers entering the store in minutes per customer is 2min/customer.

5. Abbey Road Motors pays a percent commission to its sales people. They are paid
ira [324]

Answer:

c(p) = {0.2 p ⇒ p < 1000

           0.24 p - 40 ⇒ 1000 ≤ p ≤ 2000

           0.29 p - 140 ⇒ p > 2000}

Step-by-step explanation:

* Lets explain how to solve the problem

- The profit is represented by p

1. If the profit is under $1,000,  the commission rate is 20%

∵ The profit is p < 1000

∵ 20% of p = \frac{20}{100}*p = 0.2 p

∵ c(p) is the function of the commission

∴ c(p) = 0.2 p when p < 1000

2. If the profit is at least $1,000 and less than or equal to  $2,000, the

  commission rate is 20% of the first $1,000 and 24% of the remainder

  of  the profit

- At least means greater than or equal

∵ The profit 1000 ≤ p ≤ 2000

- The commission is divided into 20% of first $1000 and 24% of

  the reminder

∵ 20% of 1000 = \frac{20}{100}*1000 = 200

∵ The remainder of the profit = p - 1000

∵ 24% of the remainder profit = \frac{24}{100}*(p-1000)

  = 0.24(p - 1000) = 0.24 p - 240

∴ The total commission = 200 + 0.24 p - 240

∴ The total commission = 0.24 p - 40

∴ c(p) = 0.24 p - 40 when 1000 ≤ p ≤ 2000

3. If the profit is above $2,000, the rate is 20% of the first $1,000

   of profit,  24% of the next $1,000 of profit, and 29% of the amount

   of profit over $2,000

∵ The profit p > 2000

- The commission is divided into 20% of first $1000 and 24% of the

  next $1,000 of profit, and 29% of the amount of profit over $2,000

∵ 20% of 1000 = \frac{20}{100}*1000 = 200

∵ 24% of 1000 = \frac{24}{100}*1000 = 240

- The amount of profit over $2,000 = p - 2000

∵ 29% of the amount of profit over $2,000 =

   \frac{29}{100}*(p-2000) = 0.29(p - 2000)

   = 0.29 p - 580

∴ The total commission = 200 + 240 + 0.29 p - 580

∴ The total commission = 0.29 p - 140

∴ c(p) = 0.29 p - 140 when p > 2000

* The commission function is:

c(p) = {0.2 p ⇒ p < 1000

            0.24 p - 40 ⇒ 1000 ≤ p ≤ 2000

            0.29 p - 140 ⇒ p > 2000}

Help for the two questions shown, please!
LekaFEV [45]

Answer:

5) 140.8m^2   6) 360in^2

Step-by-step explanation:

5.

6.4 x 6.4 = 40.96

(7.8 x 6.4) ÷ 2 = 24.96

24.96 x 4 = 99.84

99.84 + 40.96 = 140.8m^2

6.

12 x 10 = 120in

13 x 10 = 130in

5 x 10 = 50in

(12 x 5) ÷ 2 = 30in

30 x 2 = 60in

60 + 50 + 130 + 120 = 360in^2
