Which statement is true? A. Susan charges $7.50 an hour, which is higher than Jim’s hourly rate. B. Jim charges $7.00 an hour, which is higher than Susan’s hourly rate. C. Jim charges $10.00 an hour, which is higher than Susan’s hourly rate. D. Susan charges $7.00 an hour, which is equal to Jim’s hourly rate.

Answer 1

Without Jim's babysitting fee equation, we can only confirm Susan's hourly rate, which is $7.50 per hour for babysitting.

Step-by-step explanation:

The student's question requires clarification as the equation to determine Jim's fee for babysitting is not provided. However, it is possible to determine Susan's hourly rate based on the information given. Susan earns $15 for 2 hours of babysitting, which calculates to $7.50 per hour. Similarly, for 4 hours, she earns $30, which is again $7.50 per hour. This establishes that Susan's hourly rate is consistent at $7.50 per hour, regardless of the number of hours she babysits.

Answer 2

B. Jim charges $7.00 an hour, which is higher than Susan’s hourly rate.

Step-by-step explanation:

To determine this, we can calculate the hourly rates for both Susan and Jim. Susan earns $15 for 2 hours, so her hourly rate is $15/2 = $7.50 per hour. Jim's fee is given by d = 5h, which means his hourly rate is $5 per hour. Since $7.50 is higher than $5, Susan charges a higher hourly rate than Jim. Therefore, option B is true.
