Me ! a box race track charges a membership fee and and entry fee per race. one racer paid a total of $76after 3 races. another racer paid a total of $124 after 7 races. what is the entry fee (rate of change) per race how much does the track membership cost? write an equation that gives the total cost as a function of the number of races entered.

$12 per game, $40 for a membership, y = 12x + 40

Step-by-step explanation:

e = entry fee , m = membership, y = total cost

3e + m = 76

7e + m = 124

m = 124 - 7e

3e + (124 - 7e) = 76

-4e + 124 = 76

-4e = -48

e = 12

The entry fee is $12 per game

m = 124 - 7e

m = 124 - 7(12)

m = 124 - 84

m = 40

The cost of a membership is $40.

Check:

40 + 3(12) = 76

40 + 36 = 76

76 = 76

The prices are correct so the equation would be:

y = 12x + 40

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
