muminat

Answer:

$7.25

Step-by-step explanation:

Total amount spent on the ticket   = $40.75

Number of ticket purchased  = 5

Processing fee per ticket  = $0.90

Unknown:

Cost of each ticket = ?

Solution:

To solve this problem, we need to find the processing fee for the 5 tickets purchase;

      Processing fee = number ticket x processing fee per ticket

      Processing fee  = 5 x 0.9  = $4.5

Now, the real cost a ticket = $40.75  - $4.5  = $36.25

So, cost per ticket is;

        Cost  = \frac{36.25}{5}   = $7.25

I need help on this question anyone know this ?
WITCHER [35]

Answer:

y = 4(2)^{x}

Step-by-step explanation:

An exponential function in standard form is

y = a b^{x}

Use ordered pairs from the table to find a and b

Using (0, 4), then

4 = a b^{0} ( note that b^{0} = 1 ), so

a = 4, then

y = 4 b^{x}

Using (1, 8)

8 = 4 b^{1} = 4b ( divide both sides by 4 )

b = 2

y = 4 (2)^{x} ← represents the values in the table
