Armando is comparing parking prices at a local concert. Henry is charging a $7 entry fee plus $2 per hour to park in his yard. A nearby parking garage charges a $5 entry fee plus a $3 per
hour charge. The following system of equations models Armando's options.
y = 2x + 7
y = 3x + 5
a.
After how many hours will the cost of both options be the same?
b.
How much is the cost when it is the same?

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.
