the number of school delays. D, varies directly with the number of inches of snow, N. If there were 54 schools delays where there was 1.5 inch of snow, determine how many schools will be delayed if there is 4 inches of snow
+1197 Use a proportion to solve this problem.
54/1.5=x/4
54 times 4 is 216.
216/1.5=144.
So there will be 144 schools delayed if there are 4 inches of snow.
