At the city museum, child admission is 6.50 and adult admission is 9.60. on friday, 134 tickets were sold for a total sales of 1128.30. how many child tickets were sold that day?

The answer is that there there were 51 child tickets sold that day.

Step-by-step explanation:

Let c = the amount of child tickets and a = the amount of adult tickets.

c + a = 134 tickets

Solve for a:

a = 134 - c

The amount of child tickets times $6.50 and the amount of adult tickets times $960 is equal to the total dollar amount of $1,128.30. Set up the equation:

6.50c + 9.60a = 1128.30

Substitute:

6.50c + 9.60(134 - c) = 1128.30

6.50c + 1286.40 - 9.60c = 1128.30

-3.10c = -158.1

c = -158.1 / -3.10 = 51 child tickets.

Solve for a:

a = 134 - c

a = 134 - 51 = 83

Proof:

6.50c + 9.60a = 1128.30

6.50(51) + 9.60(83) = 1128.30

331.50 + 796.80 = 1128.30

1128.30 = 1128.30

35x4=140

140/20=7

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
