Explanation:
Given
Price of adult ticket = $21.00
Let x be the price of student ticket
Then
two third of the student ticket will be:
![(2)/(3) x](https://img.qammunity.org/2020/formulas/mathematics/college/ohb33xann9fhcpt19csxd5dnojmh2l4fep.png)
The statement $10.00 more than two third of student ticket:
![(2)/(3) x+10](https://img.qammunity.org/2020/formulas/mathematics/middle-school/3ozl0drgg9i1iam9dtgjf8ee88b0nh59td.png)
As we are given in the question that the adult ticket price is $21.00 and the second explanation is th equation formed by the given statement
So, both will be equivalent
![(2)/(3) x+10 = 21](https://img.qammunity.org/2020/formulas/mathematics/middle-school/g442j05npa95cttjwwvhh5bs8fx82xce8g.png)
Solving this equation for x will give us the price for the student ticket.
Hence,
C. two thirdsx + 10 = 21 is the correct answer ..
