Option D. 96 is the correct answer.
Explanation:
Let the higher grade be = x
Let the lower grade be = y
As given, The difference of the two grades is 16
or
.... (1)
The sum of one-eighth of the higher grade and one-half of the lower grade is 52.
... (2)
Putting the value of x=16+y in equation (2)






As x=16+y
x=16+80 = 96
Hence, higher grade is 96.
Each side of the cage is 2x+4 and there are 4 sides.
This means 4(2x+4) which is equal to 8x+16, the answer is <u>B</u>
$45.00 times 30% is equal to 13.5;
$45.00 less than 13.5 is equal to 31.5;
Therefore, if the pair of jeans that originally costs $45.00 are on sale for 30% off, the new cost of the jeans will be $ 31.50.
