Step-by-step explanation:
a) It is given that Alan has a total budget of $120 and he can spend this movie on concert and movies, consuming all of his money.
Cost of one concert = 40
A movie costs = 10
It means, if Alan goes to 3 concerts, he would spend entire $120 ( 3 x 40)
It means, if Alan goes to 3 concerts, he would spend entire $120 ( 3 x 40)
If Alan goes to 2 concerts, he would spend $80 (2 x 40) and remaining $40 can be used on watching 4 movies (4x10)
If Alan goes to 1 concert, he would spend $40 (1 x 40) and remaining $80 can be used on watching 8 movies (8x10)
If Alan goes to 0 concert, he would spend $0 and entire $120 can be used on watching 12 movies (12x10).
Table would be;
Concerts Movies
3 0
2 4
1 8
0 12
B.) Now using the same methodology as above, the table would be (when movie costs $5)
Concerts Movies
3 0
2 8
1 16
0 24
