Answer:
She has 36 10¢ pieces
Step-by-step explanation:
You can multiply 28 and 5 to see how much money she has in nickels.
28x5 is 140.
Now you can subtract the total amount (500) from that value:
500-140=360
now divide 360 by 10 because we are trying to find how much
10¢ coins she has
You will get your final answer as:
36 10¢ coins
