Answer 1

Variables:

number of bran muffins: x
number of blueberry muffins: y

Cost=>(1) 2x + 4y = 400

Ratio=> (2) y = 2x

Solution:

Equation (1) + Equation (2)

2x + 4y + y = 400 + 2x

=> 5y = 400 => y = 400 / 5 = 80

From equation (2) y = 2x => x = y/2 = 80/2 = 40

Answer: 40 brand muffins and 80 blueberry muffins.
