At the city museum, child admission is $5.60 and adult admission is $9.20. On Sunday, 145 tickets were sold for a total sales of $1020.80. How many child tickets were sold that day?

Respuesta :

Let x be the number of child admission tickets sold:
Child's ticket = x

There is a total of 145 tickets sold:
Adult = 145 - x

Total sales is $1020.80:
5.6x + 9.2(145 - x) = 1020.8

Solve for x:
5.6x + 9.2(145 - x) = 1020.8
5.6x + 1334 - 9.2x = 1020.8
3.6x = 313.2
x = 313.2 ÷ 3.6
x= 87

Answer: Number of child's ticket = 87



SINAZEUS
number of children ( x) is 87

number of adults (y) is 58

and this is the work ( it's a linear equation system)

hope you understand it
