Question

The admission fee at an amusement park is $4.00 for children and $5.60 for adults. On a certain day, 284 people entered the park, and the admission fees collected totaled 1360 dollars. How many children and how many adults were admitted?

Answer 1

4c+5.6d=1360
Let
Children (c)=x
Adults (d)=284-x

4x+5.6 (284-x)=1360
Solve for x
4x+1590.4-5.6x=1360
4x-5.6x=1360-1590.4
-1.6x=-230.4
X=230.4÷1.6
X=144 children

284−144=140 adults
