Final answer:
Kelly spent $32 out of a total of $80 she had originally, which means she spent 40% of her total money.
Step-by-step explanation:
To calculate the percentage of money Kelly spent, we need to determine the total amount of money she had before making her purchase. Since Kelly had $48 left after spending, and she spent $32, we add these two amounts together to find the total.
Total money = Money spent + Money left
Total money = $32 + $48
Total money = $80
Now we use the percentage formula, which is:
(Part / Total) × 100 = Percentage
In this case, the part of her total money that Kelly spent is $32, and the total is $80. So, the calculation is as follows:
(32 / 80) × 100 = 40%
Therefore, Kelly spent 40% of her total money.
