1) define variables
2) Write a system of equations to represent the situation.
3) Solve the system of equations using substitution or elimination
4) Report your answer in the context of the problem situation.

Answer 1

Explanation:

x = quarters

y = dimes

x + y = 17

.25x + .10y = 2.15

25x + 10y = 215

-25x - 25y = -425

-15y = 210

y = 14 dimes

x + 14 = 17

x = 3 quarters

(3, 14)
