Problem 1:
Emily spent $4.5 on clothes and had $15 left with her. How much money did Emily have in the beginning?

To find out how much money Emily had initially, we need to add the amount she spent to the amount she has left.

Initial amount = Amount spent + Amount left
Initial amount = $4.5 + $15 = $19.5

Problem 2:
John bought 5.5 kg of sugar. 4.5 kg of sugar was spent in making sweets. How much sugar was left behind?
#### Solution:
To find out how much sugar is left, we subtract the amount used from the total amount bought.
- Total sugar bought: 5.5 kg
- Sugar used: 4.5 kg
Sugar left = Total sugar - Sugar used
Sugar left = 5.5 kg - 4.5 kg = 1 kg

Problem 3:
Emily bought new books costing $5.4. She gave $10 to the cashier. How much change should Emily receive back?
#### Solution:

- Amount given: $10
Change = Amount given - Cost of books
Change = $10 - $5.4 = $4.6

Problem 4:
John walked 4.5 miles on the first day, 5.2 miles on the second day, and 6.2 miles on the third day. How many miles did John walk in the three days?
#### Solution:
To find the total distance John walked, we add the distances for each day.
- Distance on the first day: 4.5 miles
- Distance on the second day: 5.2 miles
- Distance on the third day: 6.2 miles
Total distance = 4.5 + 5.2 + 6.2
Total distance = 15.9 miles

Problem 5:
Peter went to a store. He bought 5.20 lbs. of jelly beans and cherries. If 3.24 lbs. were jelly beans, how many pounds were cherries?
#### Solution:
To find the weight of the cherries, we subtract the weight of the jelly beans from the total weight.
- Total weight: 5.20 lbs
- Weight of jelly beans: 3.24 lbs
Weight of cherries = Total weight - Weight of jelly beans
Weight of cherries = 5.20 lbs - 3.24 lbs = 1.96 lbs
