Answer:
298 rolls were eaten
Explanation:
we are given that Emma bought 17 packets and that in each packet, there were 18 rolls.
Hence, Emma bought,
17 packets
= 17 packets x 18 rolls per packet
= 306 rolls
We are further given that there were 8 rolls left over.
We know that,
total number of rolls in the beginning - number of rolls eaten = rolls left over.
If we substitute the known values into this expression, we will get
306 - number of rolls eaten = 8
number of rolls eaten = 306 - 8
number of rolls eaten = 298
