Answer:
$68.54
Step-by-step explanation:
If you multiply the percent, 8.8% or .088 by 63 (the price), then add the tax to the item, the total adds to 68.54
In order to obtain a ratio of boys to girls equal to 3:5, the number of boys has to be written as 3 x and the number of girls as 5 x where x is a common factor to the number of girls and the number of boys. The total number of boys and girls is 600. Hence
<span>3x + 5x = 600 </span>
Solve for x
<span>8x = 600 </span>
<span>x = 75 </span>
Number of boys
<span>3x = 3 × 75 = 225 </span>
Number of girls
<span>5x = 5 × 75 = 375</span>
The answer is C. f(n)=f(n-1)•3
Look at the photo I attached it shows how.
