The first one is correct as the service fee plus the daily cost must be added to find the total cost which is less then $160.
30s-18 is the answer jus add all the sides together/ add the like terms then solve it
6(2x-11)+15=3x+12 Given
12x-66+15=3x+12 Distribution
12x-51=3x+12 Combine like terms
12x=3x+63 addition
9x=63 subtraction
x=7 division
the value of x that makes the equation true is 7.
C= Cost
g= # of times games played
C = 0.50g + 3
C(0) = 0.50(0) + 3
C(0) = 0 + 3
C(0) = 3
This means that no games have been played yet and the entrance fee is $3
