Darnell completed 35 push-ups in one minute, which is 8 more than his previous personal best. mia completed 6 more push-ups than katie. if mia completed the same amount of push-ups as darnell completed during his previous personal best, how many push-ups did katie complete? let d represent the number of push-ups darnell completed during his previous personal best and k represent the number of push-ups katie completed.

use tape diagrams to solve the problem.

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

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
