64 muffins and 57 cupcakes. Since no muffins were sold, the amount of muffins wouldn't change. Since 15 cupcakes were sold, you just subtract 15 from the total amount of cupcakes (3 * 24 = 72; 72 - 15 = 57).
Both radio stations will play the same song on the same day <u>5 times</u> in 30 days.
<u><em>Explanation</em></u>
A radio station plays yesterday by the Beatles once every 2 days. Another station plays the same song once every 3 days.
For finding the day on which both radio stations will play the same song, we will just <u>find the LCM(Least Common Multiplier) of 2 and 3</u>. So, the LCM will be 6.
That means, <u>on every 6th day, both radio stations will play the same song</u>.
So, the number of times that both radio stations will play the same song on the same day in 30 days 
The sales tax rate of an item that costs $4 is 8%
<h2>
Explanation:</h2>
- An item costs $4 before tax
- The same item costs $4.32 after sales tax.
So the tax rate can be calculated as:
Tax rate = $4.32 - $4 = $0.32
Next, you must divide the tax rate by the original price in order to get the sales tax rate:
Sales tax rate = $0.32/4$ = 0.08
In percentage:
Sales tax rate % = 0.08x100% = 8%
