Answer:
60%
Step-by-step explanation:
Given data
we are told that 24 canisters cost $60
hence the cost per canister = 60/24= $2.5
The selling price per canister= $4
%mark up = selling price-cost price/cost price *100
Substitute
%mark up = 4-2.5/2.5 *100
%mark up = 1.5
/2.5 *100
%mark up = 0.6 *100
%mark up = 60%
Hence the percent mark up is 60%
