Here is a pro tip! When taking 10% of anything move the decimal back ONCE. The number you get is 10% of that number. You then take that number and subtract it by your original number if you want to know how much it will cost if it was 10% off.
The reason why that works is because to take 10% of something you would need to multiply it by 0.1, which is the same as 1/10 (which is also the same as dividing the number by 10).
So you take 10% of $6.00. It's $0.60.
Subtract that from your original amount.
$6.00
-$0.60
I'll let you do that one, but the answer comes out to be:
$5.40
Now to answer the question of this problem (the previous steps were if they asked for the price, but in this case you could've stopped at the 10% part)
You save $0.60.
Answer:
z = 5/2y -1
Step-by-step explanation:
We observe that z has ...
- 1 added
- the sum multiplied by 2/5
To solve for z, we undo these operations in reverse order.
If John had to mow 8 lawns, but he forgot to mow 2 lawns, we have to subtract 2 from 8 to see how many lawns he actually mowed.
8-2=6
John mowed 6 lawns!
For each lawn John mowed, he earned 3 dollars. So, we have to multiply the number of lawns he mowed, 6, by the amount of dollars he earned per lawn, 3. Multiplying 6*3 is the same as adding 3+3+3+3+3+3!
6*3=18
John earned $18!
Hope I helped! :)

So we know that there would be 225 votes.
Explanation:
225 divide 25=11
Then lastly multiply 15 with 11.
Final Result: 165 votes
