You need to make two equations- Use b for butternut squash and z for zucchini. 2b+4z = $6.96 3b=6z Solve for one of the variables in the second equation ( I will solve for b) 3b/3=6z/3 b=2z Plug it in- 2(2z)+4z =$6.96 4z+4z=$6.96 8z =$6.96 8z/8 = 6.96/8 z= .87 Plug in again - (b=2z) b= (2)(.87) b= $1. 74 So the zucchini is 87 cents and the butternut squash is $1.74 (each)
