Final answer:
The formula to enter in cell H5 to calculate the total cost by multiplying the number of participants in F5 by the cost per participant in G5 is '=F5*G5'.
Step-by-step explanation:
To answer the student's question in cell H5, the formula required to multiply the total enrolled (cell F5) by the cost per participant (cell G5) would be =F5*G5. By entering this formula, you calculate the overall cost for all participants. This type of calculation is often used in business or finance situations, such as when determining the total labor costs given hours worked and hourly rate, or the future value of an investment using a simple interest formula. Ensure that both cells F5 and G5 contain numerical values to avoid errors in calculation.
