Problema Solution
beth spent 3/8 of her money on guitar strings, 1/8 of her money on guitar picks, and $15 on a guitar tuner. How much money did Beth have before buying guitar accessories?
Answer provided by our tutors
The total money Beth had was 15$ + 1/8+3/8 meaning she spent half of her money on 2 items and the other half (15$) on a tuner
If 4/8 of her money is $15, that means the other half is also $15.
So therefore the total money Beth had was $15+$15= $30
