Question

there are 64 juice boxes at the picnic. a guest brings 4 more packs of juice that each have 8 juice boxes in them. how many juice boxes are there now?

Explanation:

Step1: Calculate new juice boxes from packs

Each pack has 8 juice boxes, and there are 4 packs. So we calculate the number of juice boxes from the new packs by multiplying the number of packs by the number of juice boxes per pack.
$4\times8 = 32$

Step2: Add to original juice boxes

We add the number of juice boxes from the new packs to the original number of juice boxes (64) to get the total number of juice boxes now.
$64 + 32 = 96$

Answer:

96
