. The new saleswoman at Clocks Unlimited was very good. During her first day on the job she sold at least two of each of the thr
LiRa [457]

Answer:

5

Step-by-step explanation:

Let the number of the kitchen clock sold =a

Let the number of the cuckoo clock sold =b

Let the number of the two-foot high grandfather clocks sold =c

The new saleswoman sold at least two of each of the three models.

Therefore:

a\geq 2\\b \geq 2\\c \geq 2

In all, she collected $300 from selling these models alone

17a+31b+61c=300

17(2)+31(2)+61(2)=218

300-218=82

Next, we try to express the remainder (82) in terms of 17, 31 and 61

82=17(3)+31

Therefore, she sold:

  • 5 kitchen clocks
  • 3 cuckoo clocks
  • 2 two-foot high grandfather clocks

She sold 5 $17 clocks.

CHECK:

17(5)+31(3)+2(61)=$300
