Tanzania [10]

Total amount of funds is $44.26 million.

Step-by-step explanation:

Given,

Donation received = $23.9 million

As it represents 54% of charity.

Let,

Total amount = x

Therefore,

54% of x = 23.9 million

$\frac{54}{100}*x=23.9\\0.54x=23.9$

Dividing both sides by 0.54

$\frac{0.54x}{0.54}=\frac{23.9}{0.54}\\x=\$44.26\ millions$

Total amount of funds is $44.26 million.
