Answer:
33.3%
Step-by-step explanation:
Given data
Cost of shoes= $60
Selling price = $100
% markup = (selling-cost/cost)*100
% markup = (100-75/75)*100
% markup = (25/75)*100
% markup = (0.33333333333)*100
% markup =33.3%
Hence the markup is 33.3%
5 + 3 + -4 + 3 + - 5+ -4 +-2 = -4
The length of the race is 5 kilometers.
5 kilometers equals 5000 meters.
Since Lana's avarege step length is about 0.5 meters, we need to divide 5000 by 0.5

Hence, Lana needs to take about
10000 steps.
