Answer:
Step-by-step explanation:
Let q represent the number of quarters. Then the number of nickels is 68-q, and the number of cents in the jar is ...
25q +5(68 -q) = 800
20q +340 = 800 . . . . simplify
20q = 460 . . . . . . . . subtract 340
q = 23 . . . . . . . . . . . divide by 20; this is the number of quarters
68-q = 45 . . . . . . . find the number of nickels
The jar contains 23 quarters and 45 nickels.
