Juan is planning to paint a room. he spends $31 on brushes, $71 on paint, and $29 on a drop cloth. Use the associative property
of addition to write two equivalent expressions that show the total cost. How can using the associative property of addition make it easier to find the total cost? what is the total cost?
the ten has to be turned into 100 to make it a percentage. so 10 times 10 is 100 and 2 also has to be multiplied by 10 which is 20. 100-20 is 80 which means 80 percent of his apples arent ripe.
