The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, $5050 is collected. Write a linear equation to find the number of children (x) and the number of adults (y) that attended the fair.

4.00(x)+1.50(y)=5050

Step-by-step solution:

4.00x800=3,200

1.50x1225= 1838

1838+3200 is 5038

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
