Melissa is betting Andrew ten dollars that he wouldn't guess the number she was thinking of. The only hint she gave him was that the number had an absolute value of 3.1. Andrew only has one guess. What should his guess be? Explain your answer

the answer is 21%.

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
