In March of 1999, Bertrand Piccard and Brian Jones attempted to become the first people to fly around the world in a hot air balloon. Based on an average speed of 97.8 kilometers per hour, the distance that they traveled in kilometers, d, can be modeled by
d(t) = 97.8t, where t is the time in hours. They traveled a total of 478 hours.
Select the option that represents the domain of the function d(t).

they will manufacture 8496 cars

step-by-step explanation:

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
