Step-by-step explanation:
let t be the price of one ticket,
since there are 4 people buying tickets in total, the price of 4 tickets would be 4t.

.
% change= (new # - original #) ÷ original # x 100
original #= 98
new #= 62
% change= (62-98)/98 x 100
= -36/98 x 100
= -0.36734 x 100
= -36.73%
Rounded to nearest 10th of %= -36.7%
