In the equation a and b represent the price per night for a room in hotel a and hotel b respectively w week s

A = $80

Step-by-step explanation:

A = 240 - 20w

B = 320 - 30w

Equate both equations

240 - 20w = 320 - 30w

Collect like terms

240 - 320 = -30w + 20w

-80 = -10w

Divide both sides by -10

w = -80/-10

w = 8

Substitute w into equation A

A = 240 - 20w

= 240 - 20(8)

= 240 - 160

= 80

A = $80

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
