A) More than 1/2 of Maria's monthly budget is spent on rent.
Step-by-step explanation:
Maria's monthly income is $2000. Half of 2000 is $1000. The amount of money she spends on rent is $900, which is $100 less than half. Therefore, A) is false, as Maria does not spend more than 1/2 of her monthly budget on rent.
She will get 23 books. So, first, you take the shipping away to get $93.05, then you divide $93.05 by $3.95 which equals 23.55 and you can't have half a book; so it's 23!
