Happy Paws charges $20.00 plus $5.50 per hour to keep a dog during the day. Woof Watchers charges $9.00 plus $6.75 per hour. Com

marta [7]

Answer:

8.8 hours

Step-by-step explanation:

Happy paws cost equation

5.50h + 20

Wood watchers cost equation

6.75h + 9

Make the two equations equal

5.50h+20 = 6.75h+ 9

Collect the co-efficient of both sides.

6.75h- 5.50h= 20-9

1.25h= 11

Divide both sides by the coefficient of h

1.25h/1.25= 11/1.25

h= 8.8

Eden needs an average of 92% on her quiz scores to earn the grade she wants in science class. Each quiz is worth 20 points.

Jlenok [28]

Answer:

19 points

Step-by-step explanation:

convert points to percents:

20 points = 100%

19 points = 95%

18 points = 90%

17 points = 85%

percent-wise, her average prior to another quiz is 92.5

so if she wants to keep to maintain that average she must get 18 1/2 points; if teacher doesn't award partial credit then she needs to get a full 19 points

A country in South America exported 62% of the 315,000 bags of coffee beans they produced in a given year. How many bags did the

Arte-miy333 [17]

Answer:

195,300

Step-by-step explanation:

62 percent *315000 =

(62:100)*315000 =

(62*315000):100 =

19530000:100 = 195300

Now we have: 62 percent of 315000 = 195300

Question: What is 62 percent of 315000?

Percentage solution with steps:

Step 1: Our output value is 315000.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above,315000=100%.

Step 4: Similarly, x=62%.

Step 5: This results in a pair of simple equations:

315000=100%(1).

x=62%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

315000/x = 100/62%

Step 7: Again, the reciprocal of both sides gives

x/315000 = 62/100

x=195300

Therefore, 62% of 315000 is 195300
