Answer: 2*(2.5 + 4.7 + c)

Step-by-step explanation:

We want to write

"Twice the sum of 2.5, 4.7 and a number c"

First:

"... the sum of 2.5, 4,7 and a number c" is written as:

2.5 + 4.7 + c

And twice "something" is written as:

2*something.

Then:

"Twice the sum of 2.5, 4.7 and a number c"

is:

2*(2.5 + 4.7 + c)

p = 100

Check:
Put 100 in for p
20 / 100 = 2 / 10; is true so 100 is correct
