Baskya tracked the number of bracelets she made each day. Does the table below show a proportional relationship between days of work and bracelets made?
| Days | 2 | 6 | 18 |
| ------ | -- | -- | -- |
| Bracelets | 30 | 90 | 150|
a) Yes, the relationship is proportional because the number of days increased by a multiple of 3 from term to term and the bracelets increased by 60 from term to term.
b) Yes, the relationship is proportional because the multiplicative factor between days and bracelets is 15 for the first two terms.
c) No, the relationship is not proportional because the unit rate is not provided.
d) No, the relationship is not proportional because the multiplicative factor between days and bracelets changes from the 1st and 2nd terms to the 3rd term (from 15 to 15 to $8 \frac{1}{3}$ ).
Answer (3)
Okay, to find the ratio, add up all the numbers of DVDs. You should end up with 36 DVDs.
The question states that you need to find the ratio between the **action DVDs **and the total amount of DVDs.
The amount of action DVDs is 12.
Now take 32 and 12, the ratio of the action DVDs and the total amount of DVDs to get your ratio.
The ratio is 12 out of 31, or 12:32
12:36 ;
The ratio of action DVDs to the total number of DVDs is 1:3. This means that for every action DVD, there are two other DVDs of different genres. Thus, action DVDs comprise one-third of Rick's total collection.
