A hotel charges a $10,000 annual fee plus an additional $200 for each night you stay there. What is the average cost per night i
Anton [14]

Answer:

\$400

Step-by-step explanation:

GIVEN: A hotel charges a \$10000 annual fee plus an additional \$200 for each night you stay there.

TO FIND: average cost per night if you stay at the hotel for 50 nights.

SOLUTION:

Annual fee charged by hotel =\$10000

amount charged each night we stay there =\$200

Total number of nights we stay =50

Total amount paid for 50 nights=50\times\$200

                                                   =\$10000

Total amount paid =\text{annual fee}+\text{total amount paid for 50 nights}

                              =\$10000+\$10000

                              =\$20000

average cost per night =\frac{\text{total amount paid}}{\text{total number of nights of stay}}

putting values,

average cost per night =\frac{20000}{50}

                                      =\$400

Hence average cost per night if we stay at hotel for 50 days is \$400

3/4 (x - 3) - 5 = 1/8 ( x - 1 )
KonstantinChe [14]

Answer:

x = - \frac{57}{5}

Step-by-step explanation:

\frac{3}{4} (x - 3) - 5 = \frac{1}{8} (x - 1)

Multiply through by 8 to clear the fractions

6(x - 3) - 40 = x - 1 ← distribute parenthesis and simplify left side

6x - 18 - 40 = x - 1

6x - 58 = x - 1 ( subtract x from both sides )

5x - 58 = - 1 ( add 58 to both sides )

5x = - 57 ( divide both sides by 5 )

x = - \frac{57}{5}

N76 [4]
Because 4.7 is the "abbreviation" for 4.70 also 4.7 is the simplified version of 4.70 kind of like a fraction you 4 70/100 simplified is 4 7/10 or 4.7.
