Please solve with work much appreciated

Answer 1

Answer:

0.046  

Step-by-step explanation:

$\text{BAC} = \dfrac{10N - 7.5H}{6.8 M}$

Data:

N = 4

H = 2

M = 80

Calculation:

$\text{BAC} = \dfrac{10N - 7.5H}{6.8M} = \dfrac{10\times4 - 7.5\times2}{6.8\times80} = \dfrac{40 - 15}{544} = \dfrac{25}{544} = 0.046$
