Final answer:
The number of sessions after which the cost at the two tennis clubs is the same can be found by setting the total cost equations of the two clubs equal to each other: x = a + b Hence the correct answer is option A
Step-by-step explanation:
To find the number of sessions after which the cost at the two tennis clubs is the same, we need to set the total cost equations of the two clubs equal to each other:
x = a + b
where 'x' represents the cost per session at the first tennis club, 'a' represents the annual fee at the second tennis club, and 'b' represents the cost per session at the second tennis club. This equation represents when the two costs are equal.
Hence the correct answer is option A
