A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 lower than in the first

Inessa [10]

Answer:

let the hotel charge before tax for second hotel be x

then the hotel charge before tax for first hotel = x+1500

tax of first hotel = 7.5% * (x+1500) = (7.5x+11250)/100

tax from second hotel= 7% of x = 7x/100

total tax = 547.50

7x/100 + (7.5x+11250)/100 =547.50

14.5x = 54750-11250

14.5x= 43500

x= 3000

hotel charge in first city = 4500

in second city =3000

sdas [7]

Answer:

Step-by-step explanation:

Here is the full question :

Asher owns a square plot of land. He knows that the area of the plot is between 4200 and 4300 square meters. Which of the following is a possible value of the side length of the plot of land? 45, 55, 65, 75

The formula of the area of a square is $length^{2}$

Given the information that the area is between 4200 and 4300 square meters, trial and error would be used to determine which of the options is correct

45^2 = 2025

55^2 = 3025

65^2 = 4225

75^2 = 5625

it can be seen that it is only 65 that is between between 4200 and 4300 square meters.
