Rex paid $250 in taxes to the school district that he lives in this year. This year's taxes were a 12% increase from last year.
Verizon [17]

Answer:

$223.21

Step-by-step explanation:

Last year the amount of taxes was x, an unknown amount. That was 100% of last year's tax cost.

This year, taxes went up by 12%, so this year the taxes are 112% of what they were last year. This year the taxes were 112% of x, and they were $250.

112% of x = 250

1.12x = 250

x = 250/1.12

x = 223.21

Answer: $223.21

If 200 vitamines cost $8.75, what should 500 vitamins cost?
WARRIOR [948]
Hello!  So, the problem is saying that 200 vitamins cost $8.75, and that is what we know.  We also know that we're going to be looking at the cost of 500 vitamins, but we don't know.  The numbers presented can be put into a proportion, and that can help solve the problem.  200 to 8.75, and 500 to a number we don't know.  I'm no sure if you familiar with the how to set up a proportion, but it's saying this number over this other number (which is a fraction) equals another fraction.  Make sure that your numbers always match up, so your not saying vitamins over money equal money over vitamins.  Use cross products, divide, and then you'll have your answer.  For this problem, since yours solving for money, make sure to have two decimal points and a dollar sign.  I hoped this helped, if you have any questions shoot me a question or message.  Good luck!
