Answer:

$54

Step-by-step explanation:

TOTAL COST

between the numbers 3 and 2

their common multiple is 6

6 pens needed ----hence a pack of 3 pens will become 12 * 2 = 24

6 files needed ---- hence a pack of 2 files will become 10 * 3 = 30

24 + 30 = 54

least amount the student must pay is $ 54
