<h3>
Answer: C) x = 80</h3>
==================================================
Work Shown:
Let's cross multiply to get the following
14/20 = 56/x
14*x = 20*56
14x = 1120
x = 1120/14
x = 80
-------------------
As a way to check the answer, we can type 14/20 - 56/80 into the calculator and we should get 0. I'm taking advantage of the rule that if A = B, then A-B = 0. This trick is handy to check if two sides of any equation are equal to one another.
Well i got 130.
hope it helps : )
9/21 simplifies to 3/7 because 9+8+4=21 and 9 is the number of daffodils and 21 is the total number and if you divide 9/21 by 3 is simplifies to 3/7
3 x 0.04 = 0.132
3+0.132 = 3.132
$3.13
