Felicia has $6.40 in dimes and quarters. She has 34 coins in all. How many of each type of coin does Felicia have? Write a system of linear equations and show all steps in the process.

Question

Define your variables and explain your solution in the context of the problem

Answer 1

x = number of dimes

y = number of quarters

x + y = 34

0.1x = value of x dimes

0.25y = value of y quarters

0.1x + 0.25y = 6.40

two linear equations

x + y = 34

0.1x + 0.25y = 6.40
