58.333.... days
Explanation:
using "scale" can solve the problem
we know that Jessie take 7 days to save 6$
lets pretend "=" as "can get"
lets say:
by the way
another way is to use a right triangle,
let the base has the width 7, each unit along the y-axis means "1 day"
let the height has the height 6, each unit along the x-axis means "1$"
now extend the height to 50 units, you will find your new big triangle has a base of 58.3...... units
this is because the tangent of the angle is the same
graph{y = 6/7x [-28.13, 103.57, -3.1, 62.7]}
