I am very sorry, but the question is not clear enough for someone to answer it.
Answer:
No solutions.
Step-by-step explanation:
we have y=3x

Answer:
50.3% of profit.
Step-by-step explanation:
English muffins are on sale for $1.99 per package, but only if you buy five packages.
Therefore, the price of five packages of muffins on sale is $(1.99 × 5) = $9.95.

So, the ordinary price per package of muffins is $(1.99 + 1) = $2.99.
Therefore, the ordinary price of five packages of muffins is $(2.99 × 5) = $14.95.
