Biology A science class performs an experiment comparing the quantity of food consumed by a species of moth with the quantity of food supplied. The model for the experimental data is y = 1.568 x − 0.001 6.360 x + 1 , x > 0 where x is the quantity (in milligrams) of food supplied and y is the quantity (in milligrams) of food consumed. (a) Use a graphing utility to graph this model. (b) At what level of consumption will the moth become satiated?

A parking garage charges a $5 flat fee, plus an additional $2 per hour.
a) Write an equation to describe the total cost (C) as a function of how many hours a
customer parks (t).
C (t) =
b) If Jimmy parks his car in this garage for 7 hours, what is the total cost?

The home prices in a certain area have been increasing at a rate of 2.1% per year for
many years. If I buy a house for $263,127 today, how much would my house have
been worth 14 years ago? (round to the nearest dollar)
