The music store bought a violin that cost v dollars. The store marked up the violin so it was 54% higher that what they bought it for. Which expression shows the cost of the violin? A. v + 0.54v
B. 1 + 0.54v
C. v + 0.54
D. 0.54v

D.

the expression is technically 54% of V. so to find the answer, we’d need to make 54% a decimal by dividing it by 100. once that’s done, we’ll be left with 0.54*v which is the same as 0.54v

Well, first of all, i am separating the parts of the question to solve them individually and then put them back together..so
3(7+4)²
  7+4 is 11. so;
3(11)²
  this is the same as 3 x 11 x 11..and that is 363. anyway;
363   *

next;
14/7
  2 *
so, we have 363-2. that is 361. so your answer is 361. hope i . have a nice day
