**Answer:**

The youngest child will receive $2000

**Step-by-step explanation:**

A father decided to give 25% of his monthly income to his three children as their monthly allowance.** **

The eldest child got 45% of the allowance and the youngest got 20%. This means that** the second child got:**

100 - (45 + 20) = 100 - 65 = 35%

The second child received $3500.

**Let the 25% of his monthly income be x.**

Hence:

35% of x = 3500

**=> **

x = $10000

The amount the man shared among his children is **$10000.**

Hence, the youngest child (20%) will receive:

20% of $10000

= $2000

**The youngest child will receive $2000**.

Answer: 2 and a half hours

Step-by-step explanation:

5/9(f-32)=c

5/9f+5/9*-32=c: step 1

5f/9-160/9=c: step 2

5f/9-160/9+160/9=c+160/9: step 3

5f/9=160/9*9+c*9: step 4

5f/5=160/5+9c/5: step 5

f=32+(9c/5): answer
