3. The table below shows information about the cost of designing and making medical face shields. a) Determine the first differences for the table to determine the cost of making each face shield.
Show your work using the table.

Number of Cost
Face Shields

33 $94.55
67 $171.05
104 $254.30

b) Determine the initial cost of designing the face shield (zero face shields made). Show how you
calculated this value.

c) Write an equation that represents this relationship

d) Use your equation from part c) to determine how much it would cost to make 84 face shields​

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
