1. Find the equation from this scenario:

Since Bobby makes $12 an hour, you know that your slope is 12 because his total pay will be the $12 multiplied by the number of hours he worked.

Add the $5 daily bonus Bobby makes, which is your y-intercept in this equation.

Total = $12(hours) + $5

2. Find his total pay for 5 hours using the above equation:

$65

The key word, "approximately," indicates that we must round each of these values. Let's round to the nearest tens place because each of our answer choices is rounded to the tens place.

Shoes cost $42.64.

$42.64 rounded (down) to the nearest tens place is $40.

Pants cost $37.99.

$37.99 rounded (up) to the nearest tens place is $40.

A shirt costs $21.34.

$21.34 rounded (down) to the nearest tens place is $20.

Let's add up our estimated prices.

$40 + $40 + $20 =

$100.

First, we want to determine Bill's income this month, independent of his stipend. We calculate his income by multiplying $30 by how many days he worked in a month. In this case, he worked 10 days. Therefore, we multiply $30 by 10, which equals $300.

Since Bill also has a consistent monthly stipend of $500, we add his income of $300 to his stipend of $500, which totals $800.

In 4 weeks, Jamie will automatically be spending $300 on rent, so we will subtract this amount from whatever income Jamie makes.

In order to calculate her income, we will multiply $60 by 5, which equals $300.

Jamie makes $300 a week.

Then we will multiply this number by 4, since we are finding her net profit over 4 weeks. $300 times 4 equals $1200.

Lastly, we subtract her rent payment ($300) from her $1200 income, making her net profit $900.

Create a linear equation to find your answer:

Since Jim makes 12 dollars per hour we can multiply 12 by the number of hours he worked. We then can multiply that number by the number of days he worked to get the total money earned.

Convert back into dollars, so you have .

Let equal the total number of hours Jimmy works in a given day. If he earns $30 per hour, then is the total amount of money Jimmy earns in a day. Given that he earned $270 on a given day:

Dividing both sides by 30:
