Answer:
There are 15 girls and 21 boys
Step-by-step explanation:
<u>Both Parts
</u><u />First, we need to know what the price is 50% off. To find this, we just need to multiply 49.99 by 50%'s decimal value (0.5).
<u>
</u><u />49.99
<u>x .5
</u><u />≈25.00<u>
Part A
</u><u />To find sales tax, we should multiply the number by the percent's decimal value. In this case, it is an 8% sales tax, which has a decimal value of 0.08.
<u>
</u><u />25.00
<u>x0.08
</u><u /><u /> 0002
Using the math above, we can see that the sales tax was $2.00.
<u>Part B
</u><u /><u />To solve for this, we need to add the sales tax back to the original price.
25.00
<u>+2.00</u>
27.00
Using the math above, we can see that the total price for the headphones is $27.00.
