Question

Bailey is counting how much money she has in change. There are​ nickels, dimes, and quarters. She has a total of ​$4 in nickels and quarters. Write an equation for how much money Bailey has in​ change, where y is the total amount of money in dollars and x is the number of dimes she has. If Bailey has ​$10 in​ change, how many dimes does she ​have

Answer 1

y = 0.05n + 0.10x + 0.25q

y = total amount of money in dollars

n = number of nickles

x = number of dimes

q = number of quarters

Since Bailey has $4 in nickles and quarters, then the rest (which is $6) is dimes

6 = 0.10x

x = 6/0.10 = 60 dimes
