Practice & Problem Solving 7. Anna Maria read 40 pages in 60 minutes. What is
her unit rate in pages per minute?

Answers

Answer 1
Answer:

Answer:

3. The unit rate is 0.67 pages per minute

Step-by-step explanation:

1. Let's check all the information given to us to solve the question:

Number of pages Anna Maria can read = 40

Time needed by Anna Maria to read those 40 pages = 60 minutes or 1 hour

2. What is  her unit rate in pages per minute?

Current speed of reading of Anna Maria = 40 pages per hour

For calculating the unit rate in pages per minute, we do the following calculation:

40 pages/60 per 60 minutes/60 (Dividing by 60 the number of pages and the time needed)

2/3 pages per minute = 0.67 pages per minute (from fraction to decimals)

3. Anna Maria can read 0.67 pages per minute

Mrs. Huynh bought a bag of 3 dozen toy animals as party favors for her son’s birthday party. The bag of toy animals cost $28.97. Estimate the price of each toy animal.

Answers

Answer:  

Step-by-step explanation:

Knowing that Mrs. Huynh bought a bag of 3 dozen toy animals. The total number of animals in the bag is:

 The cost of the bag was $28.97, so you must divide 36 by $28.97 in order to know the price of each toy animal.

To estimate this quotient, the first round the numbers so that they are easier to work with.

We can say that:

Then:

 Therefore, you can estimate that the price of each toy animal is:

Answer:

= $0.8047

Step-by-step explanation:

A dozen of toy will contain 12 toys

therefore 3 dozen of toy will contain 36 toys

now, total cost of these 36 toys are $28.97

Therefore cost of each toy = total cost of toys/ number of toys

=

= $0.8047

this will be the cost of each toy
