At the grocery store, lily spent $m$ dollars on milk, twice that amount on fruit, and $6$ dollars less than $3$ times the amount spent on milk for bread. if she entered the store with $\$80$, how much money did she have when she left? write your answer in terms of $m$.

$remaining=86-6m

Step-by-step explanation:

$remaining = 80 - (m + 2m) - (3m-6)

$remaining = 80 - 3m - 3m +6

$remaining = 86 - 6m

80 -> total amount she brings into the store

m -> money spent on milk

2m -> money spent on fruit (two x m)

3m-6 -> bread (six dollars less than three times the milk value)

Simplify and the result is 86-6m
