Multiple Choice

Before the sale, the store had 100 pairs of flip flops in stock. After selling some, they notice that  $\frac{3}{5}$  of the flip flops they have left are blue. If the store has 39 pairs of blue flip flops, what is the equation to find how many pairs of flip flops (any color) have they sold?

•  $\frac{3}{5}x-100=39$  

•  $\frac{3}{5}x+100=39$  

•  $\frac{3}{5}\left(100+x\right)=39$  

•  $\frac{3}{5}\left(100-x\right)=39$
