The table shows the amount of water in a bucket at different times. If the function has a rate of change of 2 gallons per minute, how many
gallons would be in the bucket after 4 minutes? Enter ONLY a number for
your answer.

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

=

x=0.8898305 is the answer to that equation

4y - 6 + y^2 - 9 = y^2 + 4y - 15
