Please help!!! Very much appreciated!! Natalie has a budget of $15,000 dollars to spend on tracking devices to study bison. A radio tracker costs $650 and a GPS tracker costs $1400. Natalie wants to buy at least 9 radio trackers and more than 3 GPS trackers.
The following system of inequalities represents this situation, where x is the number of radio trackers and y is the number of GPS trackers.
x ≥ 9
y > 3
650x + 1400y ≤ 15000
Which yellow shaded region corresponds to Natalie's possible choices?
