33

Step-by-step explanation:

Here, d represents the number of push-ups Darnell completed during his previous personal best and k represent the number of push-ups Katie completed,

∵ According to the question,

Darnell's current push ups = d + 8,

Mia's push-ups = d,

Katie push-ups = d + 6

Again according to the question,

d + 8 = 35 ⇒ d = 27,

Hence, the number of push-ups completed by Katie, k = d + 6 = 27 + 6 = 33
