Damari is selling popcorn for three dollars a bag. He already spent $40 in his goals to earn $85 in total arithmetic to determine how many bags he needs to sell to make his goal..

To find out how many bags Damari needs to sell, we need to subtract the amount he spent from his goal.

$85 - $40 = $<<85-40=45>>45

Damari needs to sell $45 worth of bags to reach his goal.

Since each bag costs $3, we can divide the amount he needs to sell by the cost per bag to find the number of bags he needs to sell.

$45 / $3 = <<45/3=15>>15

Damari needs to sell 15 bags of popcorn to reach his goal.

To find out how many bags Damari needs to sell to make his goal, we can use the concept of arithmetic.

Let's start by calculating how much money Damari needs to earn to reach his goal. He wants to earn a total of $85 and has already spent $40, so the remaining amount he needs to earn is:

Goal amount = Total amount - Spent amount
Goal amount = $85 - $40
Goal amount = $45

Since each bag of popcorn is sold for three dollars, we can now calculate the number of bags Damari needs to sell:

Number of bags = Goal amount ÷ Price per bag
Number of bags = $45 ÷ $3
Number of bags = 15

Therefore, Damari needs to sell 15 bags of popcorn to make his goal of earning $85.

To determine the number of bags Damari needs to sell to reach his goal, we can set up an equation based on the given information.

Let's assume the number of bags Damari needs to sell is 'x'.

The total earnings from selling 'x' bags of popcorn can be calculated by multiplying the cost per bag ($3) by the number of bags sold (x). So, Damari's earnings in terms of the number of bags sold is given by the equation:

Earnings = 3 * x

We are also given that Damari spent $40 in his efforts, so we need to subtract this amount from his earnings to get his total earnings:

Total Earnings = Earnings - $40

We know that Damari wants to earn a total of $85, so we can set up the following equation:

Total Earnings = $85

Putting it all together, we have:

3 * x - $40 = $85

To solve for 'x', we can isolate the variable by adding $40 to both sides of the equation:

3 * x = $85 + $40

3 * x = $125

Now, divide both sides of the equation by 3 to solve for 'x':

x = $125 / 3

Using long division, we find that x ≈ 41.67.

Since Damari cannot sell a fraction of a bag, we need to round up to the nearest whole number. Therefore, Damari needs to sell at least 42 bags of popcorn to reach his goal of earning $85.
