In the equations, a and b represent the price per night for a room in hotel a and hotel b, respectively, w weeks after september 1 last autumn. what was the price per night in hotel a when it was equal to the price per night in hotel b? a = 240 − 20w b = 320 − 30w

  A = B = 80 . . . per night

Step-by-step explanation:

The value of w that makes the prices equal can be found from ...

  A = B

  240 -20w = 320 -30w

  10w = 80

Substituting this value into the equation for A, we get ...

  A = 240 -2(10w) = 240 -2(80) = 80

We can check that we also get the same value for B:

  B = 320 -3(10w) = 320 -3(80) = 80

Comment on this solution

We could go to the trouble to divide by 10 to find w=8, but then we would need to multiply it by 10 again to get 20w or 30w. We can just use the result as is without the extra steps.

all but the second one

step-by-step explanation:

cuz that one goes over 180
