Total cost of limes
= (49 - 1) ÷ 2
= 48 ÷ 2
= $24
Total cost of coconuts
= 24 + 1
= $25
2 sets of limes = $24
1 set of limes = 24 ÷ 2 = $12
5 sets of coconuts = $25
1 set of coconuts = 25 ÷ 5 = $5
Difference in cost of 1 set of limes and 1 set of coconuts
= 12 - 5
= $7
Number of fruits in 1 set
= 7 ÷ 1.40
= 5
Cost of one lime
= 12 ÷ 5
= $2.40
Answer(s): $2.40
