Before the sale, the store had 100 pairs of flip flops in stock. After selling some, they notice that 3/5 of the flip flops they have left are blue. If the store has 39 pairs of blue flip flops, how many pairs of flip flops (any color) have they sold?

35

Step-by-step explanation:

Given that:

Initial number of flip flop pairs = 100

After some sale:

3/5 of flip flops left are blue = 39

The number of flip flops sold :

Let number of flip flops sold = s

Initial number - number sold = number left

Number Sold = (100 - x)

3/5 of What is left = 39

Hence,

3/5 ( 100 - x) = 39

60 - 0.6x = 39

-0.6x = 39 - 60

-0.6x = - 21

x = 21 / 0.6

x = 35
