Answer:
Regular price of the ticket is $80 .
Explanation:
As given
Heather and her family are going to the grand opening of a new amusement park.
There is a special price on tickets this weekend.
Tickets cost $56 each.
This is 70% of the cost of a regular price ticket.
70% is written in the decimal form

= 0.70
Let us assume that the cost of the regular ticket be x .
Than the equation becomes
0.70 × x = 56
0.70x = 56


x = 80
Therefore the regular price of the ticket is $80 .
