At the city museum, child admission is $5.20 and adult admission is $9.50. On Friday,133 tickets were sold for a total sales of $928.10. How many adult tickets were sold that day?

55 adult tickets were sold on Friday.

Step-by-step explanation:

A linear system will be used to model the system.

Let c be the number of child tickets and a be the number of adult tickets

Then according to given statements

From equation 1

Putting this in equation 2

Putting c = 78 in equation 1

Hence,

55 adult tickets were sold on Friday.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
