Accepted Solution
A:
b = hourly rate for babysitting and w = hourly rate for working at water park
3b + 10w = 109...multiply by -8 8b + 12w = 177...multiply by 3 ---------------------- -24b - 80w = - 872 (result of multiplying by -8) 24b + 36w = 531 (result of multiplying by 3) ---------------------add - 44w = - 341 w = -341/-44 w = 7.75 <=== hourly rate for working at water park
