Mr. Robertson goes to Math Nerds R Us to buy 85 strands of normal algebra lights plus 40 strands of radioactive algebra lights. This trip costs him $169.75. His classroom isn't bright enough, so he returns to buy another 30 normal strands and 55 radioactive strands for an additional $98.75. How much does each type of strand cost?

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
