Answer:

Rob saved $30 while he earned $75.

Step-by-step explanation:

Given:

For every 15 dollars he earns babysitting, he saves 6 dollars.

For money earned = $15

Money saved = $6

We will first find the percentage amount saved by rob

Percentage of amount is calculated by dividing money saved with for money saved and then multiplied by 100.

Percentage amount saved = \frac{6}{15}\times100 =40\%

Now we need to find the amount of money save  when money earned $75.

Amount of money saved can be calculate by multiplying money earned with percentile amount saved.

Framing in equation form we get;

Amount saved = \frac{40}{100}\times75 =\$30

Hence Rob saved $30 while he earned $75.
