Answer: 863

Step-by-step explanation:

There are two ratios in this problem, 220:500 and 380:x.

There are 220 tagged elk in a group of 500 elk counted.

There are 380 tagged elk in a group of x elk in the park.

The ratio of tagged elk to elk counted is the same as tagged elk to elk in the park. Solve for x.

Step 1: 500/220 = x/380

500/220 = 2.27

x/380 = 2.27

Step 2: Find the value of x.

x/380(380) = 2.27(380)

x = 862.6 = 863 (rounded)

Answer:

Rob saved $24 on Saturday.

Step-by-step explanation:

Given:

Rob is saving to buy a new MP3 player.

Money earned in baby sitting = $11

Money saved =$6

First we will find the Percentage of amount he saved.

Percentage of amount he saved can calculated by Amount saved divided by total money earned and then multiplying by 100.

framing in equation form we get;

Percentage of amount he saved = $\frac{6}{11} \times 100 \approx 54.55\%$

Now Given:

Money earned in babysitting on Saturday = $44

We need to find the Money he saved on Saturday.

Money Saved can be calculated by Percentage of amount he saved multiplying by Money earned in babysitting on Saturday and then divided by 100.

framing in equation form we get;

Money Saved on Saturday = $\frac{54.55}{100}\times 44 = \$24$

Hence Rob saved $24 on Saturday.
