Kent bought some guppies, angelfish and goldfish for $45. The ratio of the amount he spent on the guppies to the goldfish was 2 : 3. The ratio of the amount of money he spent on the angelfish to the goldfish was 5 : 6. The cost of each guppy was $0.80. The number of angelfish bought was 2/3 of the number of guppies bought. The number goldfish bought was 3/5 of the number of angelfish bought.

a) How much did Kent spend on each kind of fish?

b) How many goldfish did Kent buy?

c) What was the cost of each angelfish?

Needed help to solve the question above. Thank you!
