kotegsom [21]

Answer:

$X=12.125\%$

Step-by-step explanation:

From the question we are told that:

Cost Price $CP=734$

Sale Price $SP=823$

Generally the equation for Profit P is mathematically given by

$Profit=SP-CP$

$P=823-734$

$P=89$

Therefore as a percentage

Percentage Profit X is given as

$X=\frac{89}{734}*100$

$X=12.125\%$

A baker bakes 50 muffins. 1/5 of the muffins are chocolate chip. 1/2 of the muffins are blueberry. The rest are cinnamon. How ma

vitfil [10]

Answer:

15 muffins are cinnamon.

Step-by-step explanation:

Given that:

Number of muffins baked = 50 muffins

Chocolate chip muffins = 1/5 of 50 = $\frac{1}{5}*50$

Chocolate chip muffins = 10 muffins

Blueberry muffins = 1/2 of 50 = $\frac{1}{2}*50$

Blueberry muffins = 25

Cinnamon muffins = Muffins baked - chocolate chip muffins - blueberry muffins

Cinnamon muffins = 50 - 10 - 25

Cinnamon muffins = 50 - 35 = 15

Hence,

15 muffins are cinnamon.
