43. Let y represent the number of gold coins and x represent the number of silver coins: 14 y+7 x≥25,000. Since you cannot have fractional pieces of gold or silver, the reasonable domain is all whole numbers such thatx≥0, and the range is all whole numbers such
that ≥4 , y ≥−12x+1785.7.

44. Let d represent the number of days the car is to be rented and m represent the number of miles: 25d+¿ 0.30m<¿140. Miles and days are never negative so the reasonable domain is all real numbers such that m≥0, and the reasonable range is all real numbers such that 0≤d←0.012m+5.6 .
