Jasmine by strings to decorate her braids she buys 40 strings for $16 the cost of the strings is proportional to the number of strings purchased what is the constant of proportionality for the relationship between cost and number of strings a 24 B 2.5 C 0.4 D16

Answer 1

To find the constant of proportionality for the relationship between cost and the number of strings, you can use the formula:

\[ \text{Constant of Proportionality} = \frac{\text{Cost}}{\text{Number of Strings}} \]

In this case, Jasmine buys 40 strings for $16. Plugging in the values:

\[ \text{Constant of Proportionality} = \frac{16}{40} \]

Calculating this gives:

\[ \text{Constant of Proportionality} = 0.4 \]

So the constant of proportionality is 0.4.

The correct answer is C 0.4.
