Final answer:
To calculate the total price Jacob must pay for five new video games at $60 each and eight used video games at $15 each, multiply the prices by their respective quantities and add the results to get $420.
Step-by-step explanation:
To find the total price Jacob must pay for the video games, we need to calculate the cost of both new and used video games separately and then add them together. The cost of new video games is found by multiplying the number of new games by the price of each new game. The cost of used video games is determined by multiplying the number of used games by the price of each used game. Therefore, the equation is:
Total Price = (Price of New Video Games × Number of New Video Games) + (Price of Used Video Games × Number of Used Video Games)
Substituting the given values, we get:
Total Price = ($60 × 5) + ($15 × 8) = $300 + $120 = $420
Hence, the total price Jacob must pay is $420.
