Lexi purchased 1\frac{1}{2} pounds of green apples and \frac{3}{4} pounds of red ones. In total, she purchased

1\dfrac{1}{2}+\dfrac{3}{4}=\dfrac{3}{2}+\dfrac{3}{4}=\dfrac{3\cdot 2+3}{4}=\dfrac{9}{4} pounds of apples.

If apples cost $1.08 per pound, then the total cost is

\$1.08\cdot \dfrac{9}{4}=\$\dfrac{108}{100}\cdot \dfrac{9}{4}=\$\dfrac{54}{50}\cdot \dfrac{9}{4}=\$\dfrac{27\cdot 9}{50\cdot 2}=\$\dfrac{243}{100}=\$2.43.

Answer: $2.43
