Let x be the number of $2.55 notebooks and 50-x be the number of $3.22 notebooks. 2.55x+ 3.22(50-x) = 157.65 Solve the equation for x, and you will have the number of $2.55 notebooks. Subtracting that value from 50 will give you the number of other notebooks. Let me know if you need more help.

Ok, are you ok with how I arrive at this equation? 2.55x+ 3.22(50-x) = 157.65

Ok, so now we need to algebraically solve for x. 2.55x + 161 -3.22x = 157.65 -0.67x=-3.35 x=5 We remember that we let x equal the number of $2.55 notebooks sold. So 5 of them were sold. Since we sold 50 of both combined, we must have sold 45 $3.22 notebooks.
