Every weekend Greg mows and rakes lawns to earn extra money. He makes $45 for every lawn he mows and an extra $15 for raking. His goal is to earn at least $250 per week. If m represents mowing, and represents raking, which inequality models Greg's situation?
O 45m + 15n < 250
O 45m + 15n > 250
15m + 45n > 250
O 15m + 45n< 250

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
