In 1991, a box seat at the theater cost $84.50 per ticket, and parking costs were $14.50 per vehicle. If, for the 1992 season, box ticket prices went up by 18 percent and parking costs went up by 10 percent, how much more did it cost one person with one vehicle to spend a night at the theater in 1992?

A. 17.50
B. 16.66
C. 16.50
D. 16.25
E. 14.50

Sol:

18 percent of 84.50 is around 15.21
10 percent of 14.50 is 1.45
Total extra cost is 16.66 so option B is the answer

IMO : B

A. 17.50
B. 16.66
C. 16.50
D. 16.25
E. 14.50

Sol:

18% of 84.50 +10% of 14.50

(20/100)*84.50 - (2/100)84.50 =16.90 - 1.69 = 15.21

then 10% of 14.50 =1.45

so total =15.21+1.45=16.66

Option B.

If, for the 1992 season, box ticket prices went up by 18 percent and parking costs went up by 10 percent, how much more did it cost one person with one vehicle to spend a night at the theater in 1992?

A. 17.50
B. 16.66
C. 16.50
D. 16.25
E. 14.50

A person had to pay 1.18(84.5) + 1.1(14.5) dollars in 1992, whereas he or she had to pay

84.5 + 14.5 dollars in 1991.

Therefore, the increase is:

1.18(84.5) + 1.1(14.5) - (84.5 + 14.5)

Rearranging, we have:

1.18(84.5) - 84.5 + 1.1(14.5) - 14.5

84.5(1.18 - 1) + 14.5(1.1 - 1)

84.5(0.18) + 14.5(0.1)

15.21 + 1.45 = 16.66

Answer: B

A. 17.50
B. 16.66
C. 16.50
D. 16.25
E. 14.50

we just have to find the rise, not the total amount. so 18% of 84.5 = 15.21 and 10% of 14.5 = 1.45, adding up, answer = 16.66
hence B is the correct answer
