The school cafeteria buys bottles of water for $0.75 each and sells them for $1.05 each. By what percentage does the cafeteria markup the price of water bottles? Do NOT include units or percent signs!

40

Step-by-step explanation:

Cost of the bottles of water = $0.75

Sales of the bottle= $1.05

markup Price= [(Sales of the bottle)-(Cost of the bottles of water)]/Cost of the bottles of water

= ($1.05- $0.75)/$0.75

= $0.30/$0.75

=0.40×100%

40%
