Question

You are painting a room. After 18 minutes, 64% of the room still needs painted. How long does it take to paint the entire room? Write an equation that

represents the percent y of the room that still needs painted after 3 minutes.

Answer 1

Around 15.33% of the room would need to still be painted

> 18/1 = 64/100
[÷2]
> 9/1 = 32/100
[÷3]
> 3/1 = 10.67/100

> 64% + 10.67% = 74.67% painted
