Answer:
Mary has the better deal
Step-by-step explanation:
Jennifer's $1.35 * 12 = $16.20
Mary's 12 flowers = $15.96
So say we have the number: 54,321
The 5 would be worth 50,000 meaning it's in the ten thousands place.
The 4 would be worth 4,000 meaning it's in the thousands place.
.
The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place
.
Hope that helps :)
