Answer: 5 fruit baskets.
Step-by-step explanation: To find the number of baskets she purchased, we need to use inverse operations. Inverse operations are the opposite of the operations used. So, instead of:
15x + 30 = 105
we need to do:
105 - 30 = ?/15
So, 105 - 30 = 75
So, instead of multiplying, we now divide.
So, 75/15 = 5
This is how I got my answer. I hope this helps!
