Respuesta :
First, find the relationship between the number of minutes, x, she works and the number of sundaes,s, she makes
She makes s = [1sundae / 2 minutes]* x = x/2
Now find the relation of the earnings, E, with the number of sundaes she works
E = $1.20* s = 1.2s.
And finally, relate E with the number of minutes she works, x: E = 1.2 [ x/2]
E = 0.6x
Hope this helps!
