A baker made 60 muffins for a cafe. By noon, 45% of the muffins were sold. How many muffins were sold by noon?
hodyreva [135]

Answer:

27 muffins.

Step-by-step explanation:

We have been given that a baker made 60 muffins for a cafe. By noon, 45% of the muffins were sold.

To find the number of muffins sold by noon let us find 45% of 60.

\text{The number of muffins sold by noon}=\frac{45}{100}\times 60

\text{The number of muffins sold by noon}=0.45\times 60

\text{The number of muffins sold by noon}=27

Therefore, 27 muffins were sold by noon.

quester [9]
Let the number of times she turns the pedal in one mile be x.

Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then

\frac{4}{7} = \frac{x}{875}  \\  \\ \Rightarrow 7x=4(875)=3,500 \\  \\ \Rightarrow x= \frac{3,500}{7} =\bold{500}

Therefore, she turns the pedal 500 times in one mile.
