Answer 1

Answer:

$ 8,000

Step-by-step explanation:

Let x be the donation before 2 years ago,

∵ Last year, donations were 10% greater than a year before,

⇒ Donation in last year = x + 10% of x

$=x + \frac{10x}{100}$

= x + 0.1x

= 1.1x

Now, the donation is 15% greater in this year than last year,

So, the donation in this year = 1.1x + 15% of 1.1x

$=1.1x +\frac{15\times 1.1x}{100}$

$=1.1x + 0.165x$

= 1.265x

According to the question,

1.265x = 10,120

$\implies x =\frac{10120}{1.265}=8000$

Hence, 2 years ago it was raised $ 8,000.
