Answer:
The number of child tickets sold was 36
Step-by-step explanation:
The complete question is
At the city museum, child admission is $5.80 and adult admission is $9.30. On Monday, four times as many adult tickets as child tickets were sold, for a total sales of $1548.00. How many child tickets were sold that day?
Let
x ----> the number of child tickets sold
y ----> the number of adult tickets sold
we know that
[tex]5.80x+9.30y=1,548.00[/tex] ---> equation A
[tex]y=4x[/tex] ----> equation B
Solve by substitution
Substitute equation B in equation A
[tex]5.80x+9.30(4x)=1,548.00[/tex]
solve for x
[tex]5.80x+37.2x=1,548.00[/tex]
[tex]43x=1,548.00[/tex]
[tex]x=36[/tex]
therefore
The number of child tickets sold was 36
