**Answer This Question**

I really need help with this question...

Assume all 50 packets are small.

Number of sweets = 50 x 5 = 250

Now we know the total number of sweets is 302. So we need to replace some of the small packets with big packets

When we replace 1 small packet (with 5 sweets) with 1 big packets (9 sweets), the total number of sweets increases by 4.

302 - 250 = 52

We need an increase in 52 sweets.

52 ÷ 4 = 13

So we need to replace 13 small packets with big packets.

This means that there are actually 13 big packets

So number of small packets

= 50 - 13

= 37
