Answer:
4 packs
Step-by-step explanation:
3 packs only gives him 18 and he needs atleast 23. The closest number that meets 23 is 24. It takes 4 packs of 6 to get 24.
He needs four packs.
6*4=24 there is 23 so he will need 4 packs in total.
63:70
$246 / 24
= $10.25 per pack.
So the rate would be:
$10.25 : 1
Hope this helps you!
