15 over 76,894 and x over 100. You cross multiply15 with 100 which gives you 1500 and divide by the number you have left, 76,894. You get 0.0195073738. Make sure you round!

Answer:

The last year population was 66864.

Step-by-step explanation:

It is given that the population of a town grew 15% up to 76,894.

Let the last year population be x.

The population increased by 15% up to 76894.

x+\frac{15}{100}x=76894

\frac{100x+15x}{100}=76894

\frac{115x}{100}=76894

115x=7689400

x=66864.3478

x\approx 66864

Therefore, the last year population was 66864.

Vikentia [17]
To answer your question very literally, the united states only elects one president per term! The president can only serve two terms and is then forced to leave office! But if you where asking how many presidents the U.S. has had, as of 2016 the U.S. has had exactly 43 presidents and 44 presidencies (one served a second term)

Explanation and answer please :)
puteri [66]

Step-by-step explanation:

You use the I = PRN formula

P = 11 500

R = 7.25% but you have to 7.25 divide by 100 so it becomes a decimal so it should be 0.0725

N = 2 years and 6 months. This can be 2.5 years because half of 12 is 6

the solution is 11 500 × 0.0725 × 2.5 = 2084.38
