(a)  Call x the additional consecutive number of FTs she needs to make

We have this equation

 

[12 + x ] / [ 15 +  x ] = .85

 

(b)   Multiply both sides by  15 + x

 

12 + x  = .85 [ 15 + x]

 

12 + x  =  12.75  + .85x      subtract  .85x, 12 from both sides

 

.15x  = .75     divide both sides by .15

 

x  = 5  additional consecutive FTs

 

 

cool cool cool
