Widgets sell for $4 with a $9 shipping charge added on the order.
1. Write an equation that gives the total cost of an order in terms of the number of widgets. Use x to represent the number of ordered widgets and use y to represent the total cost in dollars.
C(x)=9+4x
2. Use the equation to find the total cost of an order of 12 widgets. Show all work and use complete sentences in your answer.
C(12)= 9+12*4
C(12)=57

Use your equation to find the total cost of an order of 257 widgets. Show all work.
C(257)=4*257+9
=1037
3. Use the equation to find the number of widgets that can be ordered for $89. Show all work.
C(x)=9+4x
89=4*x+9
89-9=4*x
80=4x
/4
x=20 widgets
4. Use the equation to find the widgets that can be ordered for %2069. Show all your work.
