Step-by-step explanation:
Given question is incomplete; here is the complete question.
Working together, Sam and Charlie can change all light bulbs in the office building in 3 hours. It would have taken Charlie 8 hours to do the job alone. Which equation can be be used to solve for the rate 'r', for Sam to change all the light bulbs in the office building by himself.
Let Sam can change the bulbs in the office alone in 'r' hours
Per hour work done by Sam alone =
Let Sam takes he time to change the same bulbs in the office alone = 8 hours
Per hour work done by Sam =
Since, Sam and Charlie complete the work together in time = 3 hours
Therefore, per hour work done by both =
Equation for per work done by both will be,
Per hour work done by both = Per hour work done by Sam alone + Per hour work done by Charlie
Therefore, equation for the rate 'r' will be,
Answer:
The cost of one bear is <u>$47,000</u>.
Step-by-step explanation:
The question is incomplete and the data is missing so the complete question with data is below with attached files:
To celebrate there 125 anniversary, a company in Germany produced 125 very expensive teddy bears. The bears,known as the "125 karat teddy bears", are made mohair,silk and gold thread and have diamond and sapphire eyes.
The chart shows the approximate cost of " 125 teddy bears". Based on the pattern, how much does one bear cost?
Now, to get the cost of one bear.
So, we solve it by using unitary method:
If 4 bears cost = $188,000.
Then 1 bear cost =
Thus, cost of one bear is $47,000.
Now, we check it by using another pattern of the data:
If 7 bears cost = $329,000.
Then 1 bear cost =
Hence, the cost of one bear is $47,000.
Therefore, the cost of one bear is $47,000.
