Emilio asked his aunt for $20 to buy supplies for his lemonade stand. Once his stand opened he made $40 a day
FrozenT [24]

The equation that represents profit is $40x - $20.

The profit after 5 days in business is $180.

The profit after 10 days in business is $380.

The profit after 10 days in business if revenue is $45 is $430.

<h3>What is profit? </h3>

Profit is total revenue less total cost.

Profit = total revenue - total cost

Profit = $40x - $20

Where:

x = number of days

<h3>What is the total profit after 5 days and 10 days? </h3>

$40(5) - $20

= $200 - $20

= $180

$40(10) - $20

$400 - $20

$380

<h3>What is total profit if revenue is $45? </h3>

$45(10) - $20

= $450 - $20

= $430

Round 2,042,822 to the nearest 1,000
andre [41]
To round a number to the nearest thousands, we will check the number is the hundreds position:
if the number in the hundreds position is smaller than 5, then we will convert all numbers after the thousands position to zeroes
if the number in the thousands position is equal to or greater than 5, we will add one to the thousands and convert all digits after it to zeroes.

The number we have is <span>2,042,822
Applying the above concept we will find that:
the number in the hundreds position is 8 which is greater than 5
Therefore:
</span>2,042,822 to the nearest thousands is <span>2,043,000</span>
