Answer 1

Answer: 1. Yes it shows proportional relationship because they go by 5.
2. okay.. so your answer choices are 3) 2, 4) 10, 5) -2, and 6) 8. I'M GONNA GUESS. it's going to be #3.
3. Okay so $100- 30 - 10 = $60 That means that each hat cost $6 dollars and he bought 10 of them so 10 times 6 equals 60.
4. they cost 4.50 because she bought ten of them so if you multiply 4.50 by ten you get 45 and she had 5 left over.

Hope this helped!

If the price of an object dropped 65% down to $99.99, what was the original price?

Answers

If the price of an object dropped 65% down it means that 35% is $99.99, well,
then we make a proportion and solve 99.99 multiply by 100 and divide by 35,
then we get the original price $285,7

maybe I have a mistake)

The answer is 153.83. Because if you multiply 99.99 by .65, thats the answer
