Solve for x
40 = x/ -4/7

What you wanna do is find the unit rate. The unit rate of this problem would be 5.96 / 4 = $1.49 per pound of peaches. Then you want to divide $1.49 by 2 to get the price per HALF pound. $1.49 / 2 = $0.745  which you round to $0.75 and then start back with the number $5.96 for 4 pounds and add the 75 cents for the half pound and you get $6.71

Hopefully not too confusing lol
