NISA [10]
So.. hmmm if we take "x" to be the 100% sale price before tax, $76 is really 9.5% of that

amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
76&9.5\\

solve for "x"

6 times 7 to the second power
Travka [436]
Hello!

To solve this question, we must first add the exponent into the number 7 before multiplying it by the number 6. 

7 to the second power simply means 7x7. 

7x7= 49

Now that the exponent is in the equation, we can multiply 49 by 6 to find your final answer. 

6 x 49 = 294

I hope this helps answer your question! Have a great day!

A shipment of 105 Otter box covers for I-phones has arrived. The total invoice (excluding tax, shipping, etc.) is $3,849.75.
bezimeni [28]
<span>3,849.75 </span>÷ 49.95 = 77 (Calculator)

Sense you would like it explained than the question is asking how many otter box Defender Covers where shipped in that price. So when you have that they want the amount of Otter Box Defenders than you divide the amount paid for the shipment with the amount of the otter box defender price.

I hope this is helpful.
