Answer:
a) $32,000
b) 9/25
c) 36%
Step-by-step explanation:
Hello!
A) How much did you save?
Let's see. In order to find the savings, we must subtract the new price from the original.
You saved $32,000 (a pretty good deal!)
B) What fraction of the original price was this?
To find the fraction, we must divide the new price from the original.
- 18,000/50,000
- 9,000/25,000 => SImplify
- 9/25 => Simplify
It's 9 twenty-fifths of the original price.
C) What fraction of the original price was this?
Convert the fraction to percent
- 9/25
- 9*4/25*4 => Denominator of 100
- 36/100
- 36%
Answer: 12 friends.
Step-by-step explanation:
the data we have is:
Mei Su had 80 coins.
She gave the coins to her friends, in such a way that every friend got a different number of coins, then we have that:
The maximum number of friends that could have coins is when:
friend 1 got 1 coin
friend 2 got 2 coins
friend 3 got 3 coins
friend N got N coins
in such a way that:
(1 + 2 + 3 + ... + N) ≥ 79
I use 79 because "she gave most of the coins", not all.
We want to find the maximum possible N.
Then let's calculate:
1 + 2 + 3 + 4 + 5 = 15
15 + 6 + 7 + 8 + 9 + 10 = 55
now we are close, lets add by one number:
55 + 11 = 66
66 + 12 = 78
now, we can not add more because we will have a number larger than 80.
Then we have N = 12
This means that the maximum number of friends is 12.
