Question

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**.
