One evening 1500 concert tickets were sold for the fairmont summer jazz festival. tickets cost $25 for a covered pavilion seat and $15 for a lawn seat. total receipts were $28500. how many of each type of ticket were sold? use substitution or elimination.

Tickets of lawn seat sold = 900

Tickets of pavilion seat sold = 600

Explanation:

Let be the no. of lawn seats and be the no. of pavilion seats.

According to the given question,

           ----eq 1  and

 ---- eq 2

After obtaining the two equations we can solve this by either substitution or elimination.

By substitution, put

  from eq 1 to eq 2, and solve for y, which gives

and then substitute this value in eq 1 to get

By elimination, make the coefficient of one variable say x equal in both equations, for this multiply eq 1 with 15

now eq 1 becomes

subtract this equation from eq 2 to get

and substitute this value in eq 1 to get

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
