First multiply 20% by 50: .2x50=10. Then subtract that from 50: 50-10=40. The new price is $40 :)
4(5x + 12) simplified = 20x + 48
Answer:
There are <u>80 coins</u> in her collection.
Step-by-step explanation:
We can find out how many coins are in her coin collection by first converting 5% into a fraction by moving the decimal place to the left twice. Which then we get 0.05. Then, we can set up this equation:
4 ÷ 0.05 = <u>80</u>
Now, let's check our answer:
0.05 x 80 = 4.
Yep! It checks out!
