A motel rents double rooms at $34 per day and single rooms at $27 per day. If 26 rooms were rented one day for a total of $807,

torisob [31]

Let, number of double rooms and single rooms are d and s.

d + s = 26 ....1 )

Hotel rents double rooms at $34 per day and single rooms at $27 per day.

34d + 27s = 807 ....2)

Solving equation 1 and 2, we get :

34( 26 - s ) + 27s = 807

884 - 34s + 27s = 807

7s = 77

s = 11

And d = 26 - 11 = 15

Therefore, number of double rooms and single rooms are 15 and 11.

Hence, this is the required solution.

Solve the function f(5): 2x+4x/3x

natta225 [31]

Answer:

f(5) = 11 and 1/3, or approx. 11.33

Step-by-step explanation:

$f(x) = 2x + \frac{4x}{3x}$

We can divide away x in 4x/3x:

$f(x) = 2x + \frac{4}{3}$

To calculate f(5), we substitute x with 5:

$f(5) = 2 * 5 + \frac{4}{3} = 10 + \frac{4}{3} = 11 \frac{1}{3}$

Answer: 11 and 1/3, or approx. 11.33
