If you want to evaluate what percent of 550 is 4, you can do this in two following steps.<span>
<span>First, you have to write it as a fraction: 4</span>/550.
Second, you have to transform this fraction to
percent: (4/550)*100%.
(4/550)*100% = 0.0072727272727273*100% =
0.727%
<span>The correct result is </span>0.727%.</span>
Answer:
D) P = 8b - 1000
Step-by-step explanation:
Think about it,
First off
If they spent 1000 from just buying the cookies. When you buy something you lose money. So that's -1000.
Secondly,
If they charged $8 per box that would cost an additional eight dollars each time a cutomer perchased a box. Another way to show addition is multiplication.
Ex if someone bought 7 box and 8 dollars each it could be shown as either:
1. 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7
2. 8 + 8 + 8 + 8 + 8 + 8 + 8
3. 7 x 8 or 8 x7
So 8b - 1000 would make the most sense.
Answer:
n=−5
Step-by-step explanation:
0.6(10n+25)=10+5n
Step 1: Simplify both sides of the equation.
0.6(10n+25)=10+5n
(0.6)(10n)+(0.6)(25)=10+5n(Distribute)
6n+15=10+5n
6n+15=5n+10
Step 2: Subtract 5n from both sides.
6n+15−5n=5n+10−5n
n+15=10
Step 3: Subtract 15 from both sides.
n+15−15=10−15
n=−5

We need to find 30% of 20 gallons.
1) We can write a proportion
20 gallons ---- 100%
x gallons --------30%
x = 20*30/100 = 6 gallons
2) Or we can write 30% as decimal.
30% = 30/100 = 0.3
0.3 of 20 = 0.3*20 =6 gallons
Answer 6 gallons are used efficiently.
