A shop sells pens and files only in packs. A pack of 3 pens cost $12. A pack of 2 files cost $10. A student wants to buy an equal number of pens and files. What is the least amount that the student must pay?

Respuesta :

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
