To determine how many donuts Ramon makes in 5 hours using a unit rate, we start by calculating his rate of making donuts per hour.
Ramon makes 33 donuts in 7 hours. To find the unit rate (donuts per hour), we divide the total donuts by the total hours:
\[ \text{Unit Rate} = \frac{33 \text{ donuts}}{7 \text{ hours}} \approx 4.7143 \text{ donuts per hour} \]
Next, we find out how many donuts he makes in 5 hours:
\[ \text{Donuts in 5 hours} = 4.7143 \text{ donuts/hour} \times 5 \text{ hours} \approx 23.5715 \text{ donuts} \]
Since we're looking for whole donuts, we round down to the nearest whole number, which is 23.
So, the answer is:
23
