1. how is finding the total value of the coins in timothy’s collection similar to finding the total value of coins in ralph’s collection?

a. you need to add the number of each type of coin and the value of each type of coin to find the total value of each collection.
b. you need to multiply the number of each type of coin by the value of that type of coin to find the total value of each collection.
c. you need to multiply the total number of coins in each collection by the total value of the types of coins to find the total value of each collection.
d. you need to multiply the total number of coins in both collections by the total value of the types of coins to find the total value of each collection.

Explanation:

To find the total value of a coin collection, for each type of coin, you calculate the value by multiplying the number of that coin by its individual value (e.g., number of quarters × $0.25$). Then sum those products. Option A is incorrect as you don't add the number and value of each coin. Option C is wrong because you don't multiply total coins by total coin - type value. Option D is incorrect as it involves both collections' total coins, which is not relevant. Option B correctly describes the process: multiply the number of each coin type by its value and sum for total value.

Answer:

B. You need to multiply the number of each type of coin by the value of that type of coin to find the total value of each collection.
