10. Manuel has a bowl of quarters and dimes.
There are 45 coins totaling $8.85. To find the
number of each coin, Manuel used a system of
linear equations and graphed them in the
coordinate plane.
The linear model
describes the cost
of the cab ride, c, as a function of the number of
miles traveled, m. How much will it cost Jules to
travel 16 miles in a cab?
Answer: $34.20
Based on the graph, about how many quarters are
in the bowl? Answer: 30
