Tom and Kate are meeting at 8 their grandparents house to go
on vacation.
They both live 30 miles away. Tom drives at
a rate of 40mph the whole way and Kate's
rate is shown in the table below. Who will
arrive first?

i would need to see the dot plot : )

i think asking google will you get the answer to that question

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
