Bobby wants to leave a tip for her waitress equal to 15% of the bill. bobby's bill for her lunch was $18 . how much money represents 15% of the bill?

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

sure thing bud

hope this

it should be described as a proper fraction.
