Anastasia is grocery shopping with her father and wonders how much shopping is left to do. "we already have 60 percent of the items on our list," her father says. anastasia sees 12 items in the cart.

Hi

Left to do 40% of the shopping

12 items ⇒ 60% of the items
x items ⇒ 40% of the items

60x = 12(40)
60x = 480
x = 480/60
x = 48/6
x = 8 items 

Left 8 items of the list (40% of the shopping)

Items: 12+8 = 20 items on her list

What does h hours mean
