Δx (delta x) is about a secant line, a line between two points representing the rate of change between those two points. That's a "differential" (between the two points).
dx is about a tangent line to one point, representing an instantaneous rate of change. That makes it a "derivative."
Answer:

7.2
Work: 45% x 16=
(45/100) x 16=
(45x16) / 100=
720/100=
