Question

Help me, please A movie theater decreased the size of its popcorn bags by 10%. If the new popcorn bags hold 18 ounces, how much did the old bags hold?

and Tyler's mom purchased a savings bond for Tyler. The value of the savings bond increases by 10% each year.
One year after it was purchased, the value of the savings bond was $220.
AND can you please please please please show me how you found the answer IM BEGGING YOU.

Answer 1

Movie Theater question:

the numerical value of 10% is 0.1, just as 50% is 0.5. if you multiple 20 by 0.1 you get 2, and subtract 2 from 20 you get 18.
The answer is 20 ounces.

Savings Account question:

if you multiply 0.1 by 220 you will get 10% of 220, then just add that answer to 220. so 0.1 x 220 is 22, 22+220 is 242.
The answer is $242.00

I hope this helps :)
