Hi there, here is the solution for your question.
Algebraic expression for;
Green Grass Inc. 10+12h, h being the number of hours of lawn service.
S & G Lawn Care 25+8h, h being the number of hours of lawn service.
Table:
1 hour 2 hours 3 hours 4 hours 5 hours 6 hours 7 hours 8 hours
Green Grass Inc. $22 $34 $46 $58 $70 $82 $94 $106
S & G Lawn Care $33 $41 $49 $57 $65 $73 $81 $89
If you want service for 3 hours or less, logically you would use Green Grass Inc as it would be cheaper. However, if it is 4 hours or more, S & G Lawn Care have better rates, as it would be cheaper.
Green grass inc is at first, 10+12, 10+24, 10+36 etc, the 2nd number is going up in 12? That is how many hours of lawn service.
S&G starts at 33 and goes up in incraments of 8, for each additional hour, as that is their hourly charge. Get the pattern?
