Question Dexter has 40 dimes and quarters. He has $5.20. How many quarters does he have? How many dimes does he have?

Answer: dimes = 32 quarters = 8 Step-by-step explanation: set up a system of equations: let d = # of dimes let q = # of quarters d + q = 40 .10d + .25q = 5.2 substitution method; let ‘q’ = 40 – d .10d + .25(40 – d) = 5.2 .10d + 10 – .25d = 5.2 -.15d = -4.8 d = 32 q = 40 – 32 = 8 Log in to Reply

Answer:Step-by-step explanation:32 dimes

8 quarters

Answer:dimes = 32

quarters = 8

Step-by-step explanation:set up a system of equations:

let d = # of dimes

let q = # of quarters

d + q = 40

.10d + .25q = 5.2

substitution method; let ‘q’ = 40 – d

.10d + .25(40 – d) = 5.2

.10d + 10 – .25d = 5.2

-.15d = -4.8

d = 32

q = 40 – 32 = 8
