Part b. How much do 120 $20 bills weigh? Please Help!!
To find the weight of a specific number of $20 bills, we need to use the information given in the problem.
The weight of a single $20 bill is approximately 0.5 grams.
To find the weight of multiple $20 bills, we can use the concept of a linear function. In a linear equation, we typically express the relationship between two variables (in this case, the number of bills and the weight) as a straight line.
Let's set up a linear function to find the weight of x $20 bills:
Weight (in grams) = x * 0.5
Here, x represents the number of $20 bills we want to find the weight for, and 0.5 is the weight of a single $20 bill.
Now, let's find the weight of 120 $20 bills using this function:
Weight of 120 $20 bills = 120 * 0.5
Weight of 120 $20 bills = 60 grams
Therefore, 120 $20 bills weigh approximately 60 grams.
w = .5 x
.5 * 120 = 60 grams
