Answer:
$108
Step-by-step explanation:
1 box = $12
18 boxes = 12×18 = $216
Total = 18×65 = 1170 pens
Cost price, Cp = $216
3 = $1
378 = 378/3 = $126
1170-378= 792 pens remaining
4 = $1
792 = 792/4 = $198
Total selling price, sp = 126+198 = $324
Profit = Sp - Cp = 324 - 216 = $108
Answer:
Answer is "No real Solution"
15/9 = 1.6666... (where 6 repeats infinitely)
If we're rounding to 2 decimal places, 6 will round up to 7
Therefore, B. 1.67 is your answer
