Answer:
8
Step-by-step explanation:
In total, Antony sold 10 muffins. We can do a ratio like this:
[tex]\frac{4}{10} = \frac{x}{20}[/tex]
Because there are 4 blackberry muffins. We solve.
Because 10 is directly half of 20, we can just multiply 4 by 2 because if you multiply 10 by 2, you'd get 20. 4 times 2 is 8. That's the answer.
