Let *y* is the number of tickets and *x* is the number of days.

The word the product of rate of sold by Akira (30 per day) and number of days plus Albertos sold tickets 22 represents .

The number of pages studied by Akira is .

The word the product of rate of sold by Jean (20 per day) and number of days plus Jeans sold tickets 53 represents .

The number of pages studied by Jean is .

Graph the equations on the coordinate plane which contain number of days on the *x* - coordinate and number of tickets sold on the *y* - axis, and find the intersection point.

Observe the graph, the graph appear intersect at . So, Akira will have sold more tickets than jean after 3 days.

The solution are

(a) Equations are Akira: and Jean: .

(b) The equations and and their graph is

(c) The solution is and Akira will have sold more tickets than jean after 3 days.
