You have a $150 gift card to use at a sporting goods store. You buy 2 pairs of shoes for $65. You plan to spend the rest of the money on socks. Socks cost $4.75 per pair. What is the greatest number of pairs of socks you can purchase?

\(150= 65(2) + 4.75(s)\) where \(s=\) the number of socks you can buy \(20= 4.75(s)\)
\(\displaystyle\frac{{20}}{{4.75}}={4.2105}\ldots..\)
So you can buy 4 pairs of socks. (Round down because you cant buy 0.2 pairs of socks).

True or False? Justify your answer with a proof or a counterexample. You can determine the behavior of all first-order differential equations using directional fields or Euler's method.
