Answer:
$440
Step-by-step explanation:
notes $2 - n
notes $10 - m
n + m = 80 ----------> m = 80 - n
1 - 2/5 = 3/5
![\frac{3}{5} * n = m - 8](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D%20%2A%20n%20%3D%20m%20-%208)
![\frac{3}{5} * n = 80 - n - 8 \\\\\frac{3}{5} * n + n = 72\\\\\frac{8}{5} * n = 72\\n = 45 \\m = 35\\](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D%20%2A%20n%20%3D%2080%20-%20n%20-%208%20%5C%5C%5C%5C%5Cfrac%7B3%7D%7B5%7D%20%2A%20n%20%2B%20n%20%3D%2072%5C%5C%5C%5C%5Cfrac%7B8%7D%7B5%7D%20%2A%20n%20%3D%2072%5C%5Cn%20%3D%2045%20%5C%5Cm%20%3D%2035%5C%5C)
45 * $2 + 35 * $10 = 90 + 350 = $440
.625 or if you want it in a fraction it is 625/1000
