4 . Jason gets paid \( \$ 20 \) to babysit for 4 hours. He gets \( \$ 30 \) for 6 hours and \( \$ 50 \) for 10 hours. Which equation shows how much money, \( m \), Jason gets paid per hour, \( h \), he babysits? A. \( m=4 h \) B. \( m=5 h \) C. \( m=10 h \) D. \( m=20 h \)

To find out how much Jason gets paid per hour, we can use the information given. For instance, he earns $20 for 4 hours, which means he makes $5 per hour (since \( 20 \div 4 = 5 \)). Therefore, we can conclude that the equation that represents his earnings per hour is \( m = 5h \). Now, to test the consistency, let’s check his other earnings: $30 for 6 hours also gives $5 per hour; and $50 for 10 hours still gives $5. This confirms our equation! Overall, the answer is B: \( m = 5h \).
