Question

Jane spends 1/3 of her money on snacks and 2/5 on a book. She remained with $60.00. how much money had Jane.?

Answer 1

use branching method or model. I think the answer is $90. 1u is 15.

I am not so sure.

Answer 2

or basic algebra ....

let her total amount of money be x

x - (1/3)x - (2/5)x = 60
multiply all terms by 15

15x - 5x - 6x = 900
4x = 900
x = 225
Jane had $225

check:
snacks = (1/3)(225) = 75
book = (2/5)(225) = 90 , expensive book!

amount left = 225-75-90 = 60
