Problema Solution
Victoria spent $8 on lunch, $7 on a book and $13 on her mom. Her brother gave her $10 and she spent $15 on the movies. She had $12 left. How much did she have to begin with?
Answer provided by our tutors
Let 'x' by the money Victoria began with. Then we have
x - 8 - 7 - 13 + 10 - 15 = 12
x - 43 + 10 = 12
x - 33 = 12
x = 12 + 33
x = $45
Victoria had $45 in the beginning.
