Total cost of limes
= (16 - 4) ÷ 2
= 12 ÷ 2
= $6
Total cost of avocados
= 6 + 4
= $10
2 sets of limes = $6
1 set of limes = 6 ÷ 2 = $3
5 sets of avocados = $10
1 set of avocados = 10 ÷ 5 = $2
Difference in cost of 1 set of limes and 1 set of avocados
= 3 - 2
= $1
Number of fruits in 1 set
= 1 ÷ 0.50
= 2
Cost of one avocado
= 2 ÷ 2
= $1
Answer(s): $1
