Answer:
r = 4 -2/3 a
Step-by-step explanation:
She spent in total 24 dollars. So, you can set the equation equal to 24.
? = 24
It costs $4 per pound for apples and $6 per pound for raspberries. You could represent apples as 4a and raspberries as 6r. Put this into the equation.
4a + 6r = 24
Now set the equation equal to r. You have to get r alone on one side.
4a + 6r = 24
(4a + 6r) - 4a = (24) - 4a
6r = 24 - 4a
6r = (24 - 4a)/6
r = 4 - 4/6 a
r = 4 - 2/3 a
