Question

Fiona has a jar filled with 150 coins made up of quarters and nickels. the total value of coins is $25.10. Let x Represent the number of quarters in the jar. Which equation can be used to find the number of quarters?

A. 0.25+0.05(x-150)=25.10

B. 0.05x+0.25(150-x=25.10

C. 0.05x+0.25(x-150)=25.10

D. 0.25x+0.05(150-x)=25.10

Answer 1

Option D would probably be the right choice. Because x is the variable for coins, there would be x amount of quarters, and because there are 150 coins, 150 - x would be the remainder.
