Answer:
€445.5
Step-by-step explanation:
First we calculate the increase percentage and the increase.
Increase = 450 + (10%*450)
Now we must calculate the percentage of the increase.
Increase percentage = 10% of €450 = 450*0.1 = 45
Increase = 450 + 45 = €495
Since the decrease happens to the <em>new </em>number, the decrease and the decrease percentage <em>both </em>must be to the new changed number, which is 495
Decrease = 495 - (10%*495)
Again we must calculate the percentage of the decrease.
Decrease percentage = 10%*495 = 0.1*495 = 49.5
Decrease = 495 - 49.5 = 445.5
So, the value of Erika's ski chalet after the two changes = €445.5
I believe it is the first once because if a means the amount of apples and $1.75 is the amount paid for 1 apple, this answer would be correct.
Answer:
<u>n= 4.5</u>
Step-by-step explanation:
The equation is:2(n-2)=5
Step 1- You need to do the parentheses.
The new equation is:
2n-4=5
Step 2-Next you add 4 to both sides of the equal sign.
The new equation is:
2n=9
Step 3- Now you divide by 2 into both sides and get the answer.
