Let the missing constant be x.
14 = 7% of x.
14 = 7/100 x
7x = 1400
x = 1400/7 = 200 x = 200.
Thus, there are 200 pennies in a pile.
0.07 x = 14
0.07 0.07 x = 0.07 14
x = 200
There are 200 pennies in the pile since 14 is 7% of 200. This was determined by setting up the equation 14 = 0.07 × x and solving for x . The calculations confirm that 7% of 200 equals 14.
