Maybe she can get 2 or4 or1. those ar all the possible answers
Pretty sure all of them can be a linear function since they all graph out to be a line..
The definition of a linear function can be shown through this formula: y=ax+b
$682.11
749.99•15% or .15=112.50
So 749.99-112.50=$637.49 and
637.49 • 7% or .07= 44.62 and
44.62+637.49=$682.11
I think it is 21+10=31...
