Lila need more money = $35.85
Solution:
Given data:
Cost of paint brush = $4.60
Cost of set of paints = $11.85
Cost of easel = $25.60
Total cost of all the items = $4.60 + $11.85 + $25.60
= $42.05
Total cost of all the items = $42.05
Lila already had amount = $6.20
Amount of money needed = Total cost of all the items – Lila had amount
= $42.05 – $6.20
= $35.85
Hence, Lila need $35.85 more money.
