To find the rate of lemons being used in lemons per cup of lemonade, you can use the formula:
\[ \text{Rate} = \frac{\text{Number of lemons}}{\text{Number of cups}} \]
In Jevonte's recipe, we have:
- Number of lemons = 10
- Number of cups = 15
Now, we can substitute these values into the formula:
\[ \text{Rate} = \frac{10 \text{ lemons}}{15 \text{ cups}} \]
Now, simplify the fraction:
\[ \text{Rate} = \frac{10}{15} = \frac{2}{3} \]
So, the rate of lemons being used is \( \frac{2}{3} \) lemons per cup of lemonade.
To make it clearer, you could express this as approximately 0.67 lemons per cup when expressed as a decimal. However, since your options range from 0 to 19, the best representation would be to note that it's about 0.67 lemons, which is approximately 0.7 if you're rounding.
If you need it expressed in a particular format for "representing the unit rate", please clarify how you would like to resize or display it.
