Answer:
165 is the cost of maths book
Step-by-step explanation:
let x be the total amount of money she had, out of which she spent (3x/7) on the math books, after which she remained with amount 220.
i.e (3x/7) + 220 = x
(4x/7) = 220
x = 385
total amount she had initially will be 385.
hence she spent
385 - 220 = 165
on the maths book.
