Supposed charity received a donation of $23.9 million. If this represents 54% of the charity donated funds what is the total amo
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.

How to simply 4 (2x)^3
Kruka [31]
Remember the order of operations. The first step in this problem will be to solve the exponent. 

Take (2x)^3. Remember that since there are parentheses around 2x, that means you have to cube 2 and x.

(2x)^3 = 2^3 * x^3 = 8x^3

Now multiply that answer by 4 to finish simplifying.

8x^3 * 4 = 32 x^3 

Your answer should be: 32x^3

balu736 [363]

Answer:

The answer is 4 years

Step-by-step explanation:

If we use each option to calculate the problem, we get:

125(0.88)^1 = 110

125(0.88)^2 = 96.8

125(0.88)^3 = 85.2

125(0.88)^4 = 74.96

We can see that 74.96 is approximately 75, therefore 4 years is the answer.
