Your town is deciding whether to build a new park. A sample of 100 people are asked if they would vote yes or
no to the new park. The survey results are shown on the
table. The mayor estimates that half of the people who said
they are undecided will actually vote "yes". Assume that the
mayor is correct. The town has 1,000 voters. How many
voters will say yes to building the park?

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.

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
