Answer:
Her total is now $170.54.
Step-by-step explanation:
You would do 20% of 212.94 which is 42.40 then subtract that from 212,94 to get the answer.
One way to solve this is by changing the mixed numbers to improper functions.
3 1/3 = 10/3
2 2/5 = 12/5
The next step I would take is to find a common denominator.
10/3 = 50/15
12/5 = 36/15
Now we can solve the original equation:
50/15 - 36/15 = 14/15
Since 14/15 is already simplified this is your final answer.
We have to find 100% of the number. We can use proportion to get it
3% -----------1.5m
100% -------- x
crossmultiply now
3*x=1.5*100
3x=150 /:3 divide both sides by 3
x=50m
2. Similar situation
40% ------------1000
100% -----------x
crossmultiply
40*x=100*1000
40x=100000 /:40
x=2500 - its the answer
Because of the added insulation to control the temperature inside,the cost of heating and cooling went down
Answer:
