Acup is 6.4 cm tall not included a 0.6 cm lip. cups are stacked inside one another. you may want to draw a diagram to you see how the height of the stack of cups increases select the function that represent the height of a stack of cards in terms of a number of cups in the stack

H(c) = 6.4 + 0.6c

6.4 is the constant

when the height of the cup is 18.4 the fnction is 18.4 = 6.4+ 0.6c

Subtract 6.4 from both sides

18.4 - 6.4 = 6.4 + 0.6c - 6.4

12= 0.6c

c=12/ 6

c=20

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
