Use the information in the chart to answer questions 1 and 2 below:
The chart shows the amount of money that Caleb earns when he babysits for the Hudson family.
Minutes of Babysitting 30 | 45 | 60 | 75
Pay $2.50 | $3.75 | $5.00 | $6.25
1. How much money would Caleb earn if he babysat for 2 1/2 hours?
A. $7.50
B. $10
C. $11.25
D. $12.50
2. If Caleb earned $17.50, how many hours did he babysit?
1. To calculate how much money Caleb would earn if he babysat for 2 1/2 hours, we need to find the pay rate for 150 minutes of babysitting. From the chart, we see that for 60 minutes of babysitting, the pay is $5.00. So, for 150 minutes (2 1/2 hours), the pay would be (150/60) * $5.00 = $12.50.
Therefore, the answer is D. $12.50.
2. To find out how many hours Caleb babysat if he earned $17.50, we need to calculate the number of minutes. From the chart, we see that for 75 minutes of babysitting, the pay is $6.25. Therefore, (17.50/6.25) * 75 = 210 minutes.
Since there are 60 minutes in an hour, 210 minutes is equivalent to (210/60) hours = 3.5 hours.
Therefore, Caleb babysat for 3.5 hours.
The answer is 3.5 hours.
To answer these questions, we need to determine how much Caleb earns per minute and then calculate the total amount of money based on the given time.
1. To find out how much Caleb earns per minute, we can divide the pay for 60 minutes (1 hour) by 60: $5.00 / 60 minutes = $0.0833 per minute.
Since there are 2 1/2 hours in 150 minutes, Caleb will earn: $0.0833 x 150 minutes = $12.50.
Therefore, the answer is D. $12.50.
2. To find out how many minutes Caleb babysat, we can divide the total amount earned of $17.50 by the pay per minute: $17.50 / $0.0833 per minute = 210 minutes.
Since there are 60 minutes in 1 hour, Caleb babysat for: 210 minutes / 60 minutes per hour = 3.5 hours.
Therefore, the answer is 3.5 hours.
To answer these questions using the information in the chart, follow these steps:
1. Convert 2 1/2 hours to minutes: Since there are 60 minutes in an hour, multiply 2.5 by 60 to get 150 minutes.
2. Look at the chart and find the row corresponding to 150 minutes. The pay for 150 minutes is $?
3. Use the information from the chart to find the answer to question 1.
To answer question 2:
1. Look at the chart and find the column corresponding to $17.50. This column of pay values represents the minutes of babysitting that Caleb did.
2. Use the information from the chart to find the answer to question 2.
Let's now calculate the answers to these questions step by step:
1. Convert 2 1/2 hours to minutes:
2.5 hours * 60 minutes/hour = 150 minutes
2. Find the pay for 150 minutes:
Looking at the chart, the pay for 150 minutes is $5.00.
Therefore, Caleb would earn $5.00 if he babysat for 2 1/2 hours. The correct answer to question 1 is C. $11.25.
To answer question 2, we need to find the minutes corresponding to $17.50 in the chart.
Looking at the chart, we can see that there is no exact match for $17.50. The closest values are $15.00 (for 120 minutes) and $18.75 (for 150 minutes).
Since $17.50 is closer to $18.75, we can estimate that Caleb babysat for approximately 150 minutes.
Therefore, Caleb babysat for approximately 2 1/2 hours to earn $17.50.
