I think the first one is correct. Since “three less than z squared” insinuate that the value is 3 units less than the value z^2
A nanometer (nm) is 10⁻⁹ m.
Therefore
10⁶ x 1 nm = 10⁶(10⁻⁹ m) = 10⁻³ m
By definition,
10⁻³ m = 1 mm (millimeter)
Answer: 1 millimeter
To figure out how much she spent all we have to do is add up $0.85, $4.50 and $1.50
