Answer:
40%
Step-by-step explanation:
She has sold 20 items total.
Refrigerators: 8/20 = 40%
Dishwashers: 1/20 = 5%
Dryers: 11/20 = 55%
So there is a 40% chance she will sell another refrigerator! hope this helps!!
Let x be the amount of nickels and y be the amount of quarters in a jar. Totally there are 87 coins, then x+y=87.
Since nickel is 5 cent coin and quarter is 25 cent coin, then 5x+25y=1255 ($12.55=1255 cents). Solve this system:x=87-y and 5(87-y)+25y=1255.
435-5y+25y=1255,
25y-5y=1255-435,
20y=820,
y=820÷20,
y=41,
x=87-41=46.
Answer: 46 nickels and 41 quarters.
