A theater group made appearances in two cities. The hotel charge before tax in the second city was $1000 lower than in the first

Artyom0805 [142]

Answer:

Let x = the charge in 1st city before taxes

Let y = the charge in 2nd city before taxes

Set up equation before taxes.

y = x - 1500 eq1

Set up equation for total tax paid.

0.065x + 0.06y = 378.75 eq2

Substitute eq1 into eq2.

0.065x + 0.06(x - 1500) = 378.75

0.065x + 0.06x - 90 = 378.75

0.125x - 90 = 378.75

0.125x = 468.75

x = 3750

Substitute this value of x into eq1.

y = 3750 - 1500

y = 2250

The hotel charge in city one is $3750 and the hotel charge in city two is $2250

What is the multiplication and division property of exponets?

Alexandra [31]

Mult
$(x^m)(x^n)=x^{m+n}$

div
$\frac{x^m}{x^n} =x^{m-n}$

baseically, x is the base, and m and n are bases

you can only use this property if bases are same

baseically
multiply means add powers
divide means subtract bottom power from top
