Carole needs to buy 5 scarves with $80 from her secret cash stash. if two of the scarves cost $35, what is the average amount of money carole can spend on the remaining three scarves, per scarf?

First you let the cost of each scarf be x. so that it will be easier to solve.

2x=$35

there is left 3x.

3x=$80 - $35

3*=$45

average amount = total amount of the remaining three scarves divided by total number of scarves.

3x=$45

x=$15

therefore, carole can spend an average of $15 per scarf.
