Problema Solution
At the city museum, child admission is $5.50 and adult admission is $8.70. On Wednesday, three times as many adult tickets were sold, for a total sales of $884.80. How many child tickets were sold that day?
Answer provided by our tutors
let
a = the number of adult ticket sold
c = the number of children tickets sold
three times as many adult tickets as child tickets were sold
a = 3c
for a total sales of $884.80
8.70a + 5.50c = 884.80
by solving the system of equations
a = 3c
8.70a + 5.50c = 884.80
we find
a = 84 adult tickets
c = 28 child tickets
