Based on data from 1990 to 2000, the retail cost of unleaded regular gasoline can be modeled by
R(t) = 0.035t + 1.16 dollars per gallon
and the retail cost of unleaded premium gasoline can be modeled by
P(t) = 0.034t + 1.35 dollars per gallon
where t is the number of years after 1990.†
(a) Solve the system of equations algebraically.
(t, P(t)) =

Explain what your solution means.
Our models predict that
years after 1990 the price per gallon for regular unleaded and premium unleaded will be the same price: $
per gallon.

(b) Based on your experience of purchasing gasoline, does your solution seem reasonable?
Yes
No
