Question

Mario was given some birthday

Answer 1

The answer would be option B "he was given $50 for his birthday."

Here is how:

Y=

^

Y equals the amount of money in the account.

75$+50$=

75x represents the amount of money he DEPOSITS which is in the question.

So if he deposits 75$ a week (which represents X) and he adds 50$ to it which means he has 50$ to begin with which means he got 50$ for his birthday.

Also....

Because 75x already represents X therefore it wouldn't be options A, C or D.

Hope this helps!
