Last week, Sean's homework record showed he spent 3 4/10 hours doing homework. He spent 2/10 of an hour doing science,
14/10 hours reading, and the rest of the time doing math. How
much time did he spend doing math?

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

$25 becasue a 10 increase would make it from 80 to 50
