Sean bought some plums and dragon fruits in the ratio of 3 : 5 respectively. The cost of one plum was $0.60 more than the cost of one dragon fruit. He spent a total of $49 buying the plums and dragon fruits. The total cost of the dragon fruits was $1 more than the total cost of the plums. How much did one plum cost?

	Plums	Dragon Fruits	Total
Number of sets	3 sets	5 sets
Compare each	$0.60 more
Total value		$1 more	$49

Total cost of plums
= (49 - 1) ÷ 2
= 48 ÷ 2
= $24

Total cost of dragon fruits
= 24 + 1
= $25

3 sets of plums = $24

1 set of plums = 24 ÷ 3 =  $8

5 sets of dragon fruits = $25

1 set of dragon fruits = 25 ÷ 5 = $5

Difference in cost of 1 set of plums and 1 set of dragon fruits
= 8 - 5
= $3

Number of fruits in 1 set
= 3 ÷ 0.60
= 5

Cost of one plum
= 8 ÷ 5
= $1.60

Answer(s): $1.60
