Question 1095593: an amusement park charges 6.00 for each child's admission and 8.00 for each adult admission. One day they sold c children's admissions and a adult's admission. There were d discount coupons valued at 1.25 each that were applied to admission costs. That day, the park had revenue of 4063.50 from the admission sales. Which equation could be used to show this situation?

.
The equation you are asking for is

6*a + 8*d = 4063.50 + d*1.25     (dollars).


     But notice that the equation contains two unknowns, a and c  (if they really are unknowns, as it usually happens in such problems).

     Then one equation is not enough to solve for TWO unknowns.

     Therefore, the additional info might be needed to make the problem posed correctly.
