Bus tickets cost $3 for an adult and $2 for a child. There are a adults and c children on a bus.
The total number of people on the bus is 52.
The total cost of the 52 tickets is $139.
Find the number of adults and the number of children on the bus.
***
let x=number of children on the bus
52-x=number of adults on the bus
..
2x+3(52-x)=139
2x+156-3x=139
x=17
52-x=35
number of children on the bus=17
number of adults on the bus=35
