Monica has been saving her spare change. So far she has saved 40 coins for a total of $6.25. Some of the coins are quarters (25 cents) and the rest are dimes (10 cents). How many of each coin does she have?
Use elimination to solve.

{q+d=40
{25q+10d=625

Answer 1

Answer:

10 quarters

40 dimes

Step-by-step explanation:

q + d = 40

25q + 10d = 625

25 > 10

q < d

25(10) = 250

10(40) = 400

$2.50 + $4.00 = $6.00
