Last week, in your job at a darkroom, you printed the following numbers of photographs:

| Day | Number of prints made |
|------|------------------------|
| Mon | 17 |
| Tue | 21 |
| Wed | 19 |
| Thur | 21 |
| Fri | 19 |

On average, about how many prints did you make per day?

A. 11
B. 19
C. 21
D. 24
E. 32



Answer :

Sure! I'll guide you through the solution step by step.

First, we need to calculate the total number of prints made over the week. Here's the data provided:

- Monday: 17 prints
- Tuesday: 21 prints
- Wednesday: 19 prints
- Thursday: 21 prints
- Friday: 19 prints

To find the total number of prints, we add up the numbers for each day:

[tex]\[ 17 + 21 + 19 + 21 + 19 = 97 \][/tex]

So, the total number of prints made during the week is 97.

Next, we need to find the average number of prints made per day. To do this, we'll divide the total number of prints by the number of days (which is 5):

[tex]\[ \text{Average prints per day} = \frac{\text{Total prints}}{\text{Number of days}} = \frac{97}{5} = 19.4 \][/tex]

So, the average number of prints made per day is 19.4.

Now, we need to determine which of the given choices (11, 19, 21, 24, 32) is closest to this average:

The possible choices are:
- 11
- 19
- 21
- 24
- 32

Comparing these to 19.4, we find that 19 is the closest value to 19.4.

Therefore, on average, you made about 19 prints per day.
