Final answer:
To find the number of scrunchies Laiyanna began with, we can use the information given in the problem. Laiyanna gave Lizzy 3/14 of her scrunchies, which is equal to 15 scrunchies. Setting up a proportion, we can determine that Laiyanna began with 70 scrunchies.
Step-by-step explanation:
To find the number of scrunchies Laiyanna began with, we can use the information given in the problem. Laiyanna gave Lizzy 3/14 of her scrunchies, which is equal to 15 scrunchies. We can set up a proportion to solve for the total number of scrunchies Laiyanna began with.
First, we set up the proportion:
3/14 = 15/x
Next, cross-multiply and solve for x:
3x = 210
x = 70
Therefore, Laiyanna began with 70 scrunchies.
