Answer:
D
Step-by-step explanation:
To evaluate note that:
Use following properties:
1)
2)
Then
Since you have
Because the spacing is in inches, the total length of the string is 28 * 12 = 336 inches long
subtract the distance to the first light: 336 - 16 = 320 inches left
the spacing is 4 inches so now you would divide the length by the spacing to get the quantity of lights:
320 / 4 = 80 lights
