PLEASE HELP!!!!!!!!!!!!!!!!!! Option 1: $35 monthly fee plus $4/hr for court rental. Option 2: No monthly fee but $6.50/hr for court rental. Let x= hrs per month of court rental time. Write an equation representing the total monthly cost,C,

What is ur answer @nburgher?

OpenStudy (anonymous):

35.00+4.00x and 6.50x

OpenStudy (ajprincess):

ya u r right:) C=35+4x C=6.50x

OpenStudy (anonymous):

ok how many hrs would u have to rent the court so that the monthly cost of option 1 is less than option 2

OpenStudy (anonymous):

is the equation \[35+4x < 6.50x\]

OpenStudy (ajprincess):

ya the inequality is this

OpenStudy (anonymous):

so \[x < 14 hrs\]

OpenStudy (ajprincess):

nope it is x>14

OpenStudy (ajprincess):

35+4x<6.5x 35+4x-4x<6.5x-4x 35<2.5x 35/2.5<x 14<x

OpenStudy (anonymous):

so by moving the x to the other side you have to change the sign from < to >

OpenStudy (ajprincess):

ya
