Final answer:
When no peaches are bought, the equation simplifies to 6y = 96. Dividing both sides by 6 gives us y = 16, so 16 blueberry packages can be bought with $96.
Step-by-step explanation:
If no peaches (x) are bought, the equation 4x + 6y = 96 simplifies to solving for y in 6y = 96, as x is 0. To find the number of blueberry packages (y) that can be bought with $96, we divide both sides of the equation by 6:
6y / 6 = 96 / 6
y = 16
So, if no peaches are bought, 16 packages of blueberries can be bought with $96.
