Write an equation to represent the following situation:
Lisa bought 2 pounds of apples and 4 pounds of pears for $20. We don't know the cost per pound at the
* = cost per pound (apples); y cost per pound (pears)
amount Lisa spent on apples,
- amount Usa spent on pears
Because she spent a total of $20, the equation is
-20
If we know the value of one variable, we can use it to find the value of the other varable to see
suppose we know that apples cost $2.50 per pound Substitute for x and solve to find y
X +
So, it apples cost $2.50 pet pound,
ya
pears cost
Det po
- 5+
