Mandy has 24y cents. She buys x kg of potatoes that cost 36 cents per kg. Express (in cents) in factorised form, how much money Mandy has now.

Can you give more clues, because i cannot solve the q with many unknowns.    

explanation:

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.
