3. The cafeteria is making 20 batches of chocolate \( c \) cookies for the 6th grade. If each batch requires \( 2 \frac{1}{2} \) cups of chocolate chips, how many total cups of chocol chips will they need?

To find the total number of cups of chocolate chips needed, we need to multiply the number of batches by the amount of chocolate chips required per batch. Given: - Number of batches = 20 - Amount of chocolate chips per batch = \( 2 \frac{1}{2} \) cups First, let's convert the mixed number \( 2 \frac{1}{2} \) to an improper fraction: \[ 2 \frac{1}{2} = \frac{5}{2} \] Now, we can calculate the total number of cups of chocolate chips needed: \[ \text{Total cups of chocolate chips} = 20 \times \frac{5}{2} \] Let's calculate this. Calculate the value by following steps: - step0: Calculate: \(\frac{20\times 5}{2}\) - step1: Multiply the numbers: \(\frac{100}{2}\) - step2: Reduce the fraction: \(50\)
