Answer :
Lukic starts off with $50, he gives $10 to Ms. Ferrando. 50 - 10 = 40. He’s left with $40 after this exchange. He gives $3 to three people. 3 x 3 = 9. 40 - 9 = 31. He’s left with $31. Ms. Sanchez pays him $7 to buy her a book.
We do not add nor subtract 7 from the answer as when it’s given it is spent immediately. There’s no point in adding 7 then subtracting it.
He is left with $31.
