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 Alberto
s 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.
