Rainbow [258]

Answer:

$13,500.

Step-by-step explanation:

Let x represent money spent on monthly bills.

We have been given that last month a museum received €21000 in donations. The ratio of bills to donations was 5:14.

We will use proportions to solve our given problem.

$\frac{\text{Bills}}{\text{Donations}}=\frac{5}{14}$

$\frac{x}{21000}=\frac{5}{14}$

$\frac{x}{21000}*21000=\frac{5}{14}*21000$

$x=5*1500$

$x=7500$

Now, we will subtract $7500 from donations to find the amount spent on new exhibitions as:

$\$21,000-\$7500=\$13,500$

Therefore, they spent $13,500 on new exhibitions.
